| Subject: | Kreem Problem Again |
I have a KFIV speedster (purchased from orig builder about a yr ago) completed
in 2001, and have discovered the "kreem" is coming off in at least the right side
tank. I also have the mil-h-6000 fuel lines so I am going to replace those
even though on initial inspection they appear to be ok. I'm not sure about the
left tank, it looks ok from what I can see, but I'm going to try to come up
with a "mini-webcam" to visually inspect the inside of the tank. I have read as
many of the posts on these subjects as I could find, but most were going back
several years, so I would like to ask the following:
1) Which is the better solvent for the Kreem, MEK or acetone?
2) Approx how long(solvent in contact with kreem) does it take to dissolve (talking
minutes, hours or days?) 2) Has
anyone successfully re-sloshed a tank after it had been in use for several
years?
Thanks to everyone who posts on this forum, as it has been very helpful!

Hi Paul,
MEK not acetone. You will not dissolve the Kreem. It is meant to stand up to most
all fluids or it wouldn't be any good. Sounds like some one didn't do a good
job of pre-cleaning or sloshing the tank the first time. It should not peal
or flake.
Get as much of the loose Kreem out as possible. Use the MEK to clean the tank,
but it is not necessary to leave it in long periods and depending on the tank
material might be harmful to do so. You can re-slosh your tank with out any problems.
Just do a good job of sloshing and rotating the tank. Do it at least three
times in one day. Rotate slowly and completely.

I agree with Roger, but will just add a couple things. First, Acetone will
work, but not near as well as MEK. Kreem is MEK based, but more expensive
than acetone and not as easy to find. If you can find MEK it will make the
job easier, but keep it away from your paint job.
Also, when you re-slosh (recommended), I would advise diluting the Kreem
50/50 with MEK. Kreem as it comes from the can is quite thick and difficult
to cover the whole inside of the tank without having thick spots, which you
don't want. By diluting it, it covers the whole inside of the tank easily
and makes it much easier to pour out the what isn't needed.
Good luck,

Like Deke, I agree with most, but I tend to disagree on the MEK vs Acetone
issue. After reading this thread, I went to the hangar and poured a little
Kreem in a cup and added some Acetone. It thinned it just like MEK would.
I also ran a small test to see if it would remove the Kreem from some small
parts I had. It did. So as far as the MEK and Acetone question, the choice
is yours - in my opinion. If you want to check to make sure, fish a couple
of flakes of the Kreem from the tank and soak it in a small amount of
acetone to see what happens.
I resloshed one tank in the mid life of my Model IV and used Acetone to
clean out the old Kreem. The primary reason I used acetone was cost. I
could tell the Kreem rinsed out by the color of the several rinses getting
less white, and the absense of white color on the surface of the tank
interior. Put plugs in all tank outlets and keep in mind that while
removing the Kreem (at least with acetone) a slight pressure will be built
up and you will want to vent the tank a couple of times with each rinse.
Cover top and bottom of the tank with plastic attached carefully with
masking tape to protect the surface as Deke mentioned.
It will take at least two of you to do the rinse and sloshing and preferably
big guys. Those wings are heavy when holding them and moving them around to
get the Kreem out and resloshing. It would help to have some sort of stand
to put the wing on to rest your arms from time to time.
I think I used about three gallons of Acetone in three separate rinses.
One last thought, I made a gimbal device that attached to the outboard end
of the wing that was attached to castored stand. This stand supported the
wing for easy removal and then allowed for one end of the wing to be
supported as it was sloshed. I still have the gimbal and would be happy to
send it to you if you think it would help - the stand became a work bench.

MEK - methyl ethyl ketone is probably a little better as regards to saturation
and
hence is a little faster acting than acetone and should require fewer slosh, rinse
drain cycles than acetone. Prolonged MEK exposure to some composites can cause
swelling and softening. MEK is probably at least twice the unit cost of acetone
but
should require about a third less. Now here is the real kicker - MEK is very toxic
and
exposure effects are cumulative. One should not breathe any vapors and it passes
right
through your bare skin into your bloodstream. You can die from a single exposure
event. You must be very careful using it and have a safety plan. MEK is very flammable
too and the flames are totally invisible. Acetone is less flammable but still it
presents a risk.
> 2) Approx how long(solvent in contact with kreem) does it take to dissolve (talking
> minutes, hours or days?)
Both MEK and acetone start to soften and dissolve the kreem surface immediately.
The
one time I watched the process was on aluminum tanks with rivet construction. The
tanks were going to be modified for more capacity. The tank size started at 11
gallons
and was expanded to 17 gallons. The tanks were removed from the wing, openings
sealed
and first flushed with under a quart of MEK for 5 to 10 minutes of rotation then
left
to sit about 20 minutes or so then rotated again for 5 minutes after opening to
the
fill cap to release the pressure. That process exposed the cap seal to MEK and
it
began to leak. Then the tank was drained and I was surprised that what was drained
out
was about the thickness of latex wall paint. The process would have continued but
by
now the tank filler cap gasket was totally destroyed and a temporary fix had to
be
done to continue. The solution was a leather gasket made from an old work shoe.
The
second rinse was repeated with close to a quart and a half of MEK and the drainage
was
not thick and the inside of the aluminum tank looked pretty clean with sort of
a
frosting everywhere and a tiny bit of kreem remaining at the edge of some of the
rivets but it might have been liquid there too. The third rinse was with about
a pint
of MEK and that was done for three sessions of rotating at least 5 minutes and
a rest
of 1 to 20 minutes. There was nearly nothing discoloring the drained MEK and the
inside of the tanks appeared shiny clean.
After the tanks were opened, welded and rivets added they were resloshed and the
result appears to be permanent.
I don't know if you could follow this same procedure with fiberglass tanks or not.
Might have to not soak them so long. At the time I saw this done, I was not aware
of
the level of toxicity of MEK although I used some kind of plastic gloves and a
respirator when I helped. I didn't get any on my skin but I sure got to know the
smell
of it. Painters using MEK use a forced fresh air supply piped into their clothes
so
they get zero exposure to it.
I was lead to believe that even though the MEK was more expensive, you needed less
and
the dissolving time was faster. I don't know from experience though.
> 2) Has anyone
> successfully re-sloshed a tank after it had been in use for several years?
I have no experience with fiberglass tanks at all. It's sure been reported to occur
plenty of times over the years on this mail list though.

Good post Paul. Do you have any documentation that MEK is toxic, or at
least any more than Acetone? I haven't been able to find anything other
than anecdotal. No, I don't plan on making any mixed drinks with it, but
I've smelled a lot of that stuff and I'm still here. Then again, I don't
let any more get on my skin that I have to. Just being cautious.

No, other than the allegation that there have been cases of a toxic shock nature

were fatal.

MEK is regarded by PNL (Battelle, Richland) to have significant exposure risk as
compared to acetone.
I did not refer to any MSDS for my posting and should have as Lowell has pointed
out.

Here's an MSDS link for MEK. It's not a friendly chemical, but

Just wear protective gloves and safety glasses (in case of it

Can't say that I've ever tried to sync them in 350 hours. Nor have I
ever seen a reference to syncing a 582 in the Rotax or CPS
literature. I make sure the carbs open the same amount, but that's
it. I've occasionally wondered if syncing was beneficial.
Regarding the miss, check the plug wires where they exit the module.
They use the crappy screw-on type connector and can easily come apart
in handling. Also check, using a needle, continuity in the wires
coming from the coil to the ignition modules. These can break inside
their covers.

I think MEK is the best choice for cleaning Kreem coated tanks simply
because of the fact that Kreem is MEK based.
However, listen up!
I believe MEK killed my brother. Please use MEK with all reasonable
protective measures available. Do not breath the stuff, get it on your skin or
expose your eyes to it's vapors.
I have written about this death to the list in the past. MEK causes
permanent damage to the brain, nervous system, kidneys, eyes and liver. These
warnings are right on the MEK container.
My brother Tom was a licensed A&P mechanic. He chose to overlook all of
the warnings and used MEK almost daily without protecting himself. He
said: "You don't even smell the stuff after awhile". He loved the superior
solvent that it is and used it to soak engine fuel injection system parts in.
I can still picture him pouring a few gallons of the stuff in the parts w
ashing tub and scrubbing fuel injectors with a brush and his bare hands.
He'd hook up an injector to pressure with MEK as a medium and watch the
perfect conical spray pattern in the bright light. He enjoyed doing the typical
hanger rash repairs to aircraft by wet sanding wing tips, wheel pants etc.
with MEK. He did a final wipe down with an MEK soaked rag, mixed the
paint with MEK for thinning and sprayed on the paint. He had all of the hanger
exhaust fans running and thought the concentrations that he exposed
himself to were small.
At the end of his day he would wash the grease out of his hands and finger
nails with a wash up session at the parts washing tank. He used to laugh
at my concerns that he should use more caution. He was just 29 years old
and a pretty cocky but, very talented guy. Pretty bull headed!
Tom's work was stressfull much of the time. He had to be right with his
troubleshooting and quick with emergency repairs. Aircraft owners want
things done yesterday. Tom began to experience heart burn problems and
indigestion pains. The human liver produces enzymes for digestion. No one saw
it
coming. I told him to stop eating the beanie weinnies out of the machine
in the hanger. I told him to take time to eat a balanced meal. The pain
persisted and his gut began to swell. I teased him about too much beer even
though he drank little of it.
Inside of two years time he was dead from liver failure. His death came
on the morning of his 30th birthday June 19, 1992. His only daughter
graduated from high school this year, 2009. She is a straight A student and
beautiful. I wish she had known her daddy. He was a terrific guy!
No autopsy was performed due to the shock that the whole family was in.
His doctor told me MEK was the likely culprit.
People can smoke their entire lives and not get lung cancer. You can lay
in the sun for days and not get skin cancer. You can use MEK to slosh your
tanks and not damage your eyes or liver. Tom saturated himself with the
stuff. For me, I think I'll use a pressurized fresh air supply mask and
gloves.

Both MEK and acetone start to soften and dissolve the kreem surface
immediately. The
one time I watched the process was on aluminum tanks with rivet
construction. The
tanks were going to be modified for more capacity. The tank size started
at 11 gallons
and was expanded to 17 gallons. The tanks were removed from the wing,
openings sealed
and first flushed with under a quart of MEK for 5 to 10 minutes of
rotation then left
to sit about 20 minutes or so then rotated again for 5 minutes after
opening to the
fill cap to release the pressure. That process exposed the cap seal to MEK
and it
began to leak. Then the tank was drained and I was surprised that what was
drained out
was about the thickness of latex wall paint. The process would have
continued but by
now the tank filler cap gasket was totally destroyed and a temporary fix
had to be
done to continue. The solution was a leather gasket made from an old work
shoe. The
second rinse was repeated with close to a quart and a half of MEK and the
drainage was
not thick and the inside of the aluminum tank looked pretty clean with
sort of a
frosting everywhere and a tiny bit of kreem remaining at the edge of some
of the
rivets but it might have been liquid there too. The third rinse was with
about a pint
of MEK and that was done for three sessions of rotating at least 5 minutes
and a rest
of 1 to 20 minutes. There was nearly nothing discoloring the drained MEK
and the
inside of the tanks appeared shiny clean.
After the tanks were opened, welded and rivets added they were resloshed
and the
result appears to be permanent.
I don't know if you could follow this same procedure with fiberglass tanks
or not.
Might have to not soak them so long. At the time I saw this done, I was
not aware of
the level of toxicity of MEK although I used some kind of plastic gloves
and a
respirator when I helped. I didn't get any on my skin but I sure got to
know the smell
of it. Painters using MEK use a forced fresh air supply piped into their
clothes so
they get zero exposure to it.
I was lead to believe that even though the MEK was more expensive, you
needed less and
the dissolving time was faster. I don't know from experience though.

I have no experience with fiberglass tanks at all. It's sure been reported
to occur
plenty of times over the years on this mail list though.

"To take from one, because it is thought his own industry and that
of his fathers has acquired too much, in order to spare to others,
who, or whose fathers, have not exercised equal industry and
skill, is to violate arbitrarily the first principle of
association, the guarantee to everyone the free exercise of his
industry and the fruits acquired by it."

"We maintain our strength in order to deter and defend against aggression
-- to
preserve freedom and peace. Since the dawn of the atomic age, we've sought
to
reduce the risk of war by maintaining a strong deterrent and by seeking
genuine
arms control. 'Deterrence' means simply this: making sure any adversary who
thinks about attacking the United States, or our allies, or our vital
interests, concludes that the risks to him outweigh any potential gains.
Once
he understands that, he won't attack. We maintain the peace through our
strength; weakness only invites aggression."

"The Founding Fathers established a system which meant a radical
break from that which preceded it. A written constitution would
provide a permanent form of government, limited in scope, but
effective in providing both liberty and order. Government was not
to be a matter of self-appointed rulers, governing by whim or harsh
ideology. It was not to be government by the strongest or for the
few. Our principles were revolutionary. We began as a small, weak
republic. But we survived. Our example inspired others, imperfectly
at times, but it inspired them nevertheless. This constitutional
republic, conceived in liberty and dedicated to the proposition
that all men are created equal, prospered and grew strong. To this
day, America is still the abiding alternative to tyranny. That is
our purpose in the world -- nothing more and nothing less."
-- Ronald Reagan

I want to thank everyone who has responded to my questions as the input has been
very helpful. I checked the msds sheets on both acetone and the mek and they
were very similar..both rate the health risks as a "2" . I checked Lowes website
and they show mek in 5gal for $99 and acetone in 1 gal for $16.98, so if they
actually have them in the stores for those prices, there isn't much difference
as far as cost. Again, thanks to everyone, but if someone else has personal
experience with this type problem, please go ahead and reply and will take
all the advice I can get.

Hi Ed, the mechanical synro of the Bing 54 carbs works very well, and can be do
with the engine NOT running, just remove the air filters and check that both
carbs start to open at the same time then measure at the half way point and then
again at full throttle if both carbs are adjusted so they are the same it
will be good to go. As Guy posted I'd check for an ignition problem as far as
the miss and starting on one cyl which is not normal. Good luck.
