Hi TG:
I can also trot, but that is a horse of a different color.

Gents,
While I've got my engine off, I'm planning on doing some work on the
firewall. So far, I've been using scotch-brite pads to remove the surface
corrosion, but was wondering if there was some better techniques, especially
as I get the rough stuff off, and begin getting it nice and smooth. Then,
after that's taken care of, I was looking at options for painting (or not)
the firewall to keep the corrosion from happening again. I've noticed a
couple of aircraft that have painted firewalls, and was wondering if that
was a good idea. Is there a way to keep the metal finish and still fight
the corrosion? I've planned on getting the engine mount magnafluxed and
repainted as well.
Anyway, any ideas/experiences are welcome.

Regarding Steven's question, I have appreciated having the entire interior
of my cowl, upper, lower and firewall all finished in gloss white.
It's relatively easy to keep clean and hardly a fleck of dust nor a drop of
oil can escape my scrutiny.

Thanks Bob, I'll take that on board. What type of paint/prep did you use
for that?

Steve, I have painted several firewalls and although it is quite a bit of
work it is worth it if done properly. I typically use an epoxy primer (used
by Boeing, I forgot the name but can get it) and then top coat it with
DuPont Imron if you want the most finished look. I just sand the firewall
and then use scotchbrite and a stainless wire brush to clean around the few
rivets, etc. It needs to be thoroughly cleaned with lacquer thinner before
painting. I also take off almost everything that can be unbolted readily
like the starter and master relays, the battery box, primer line, wiring
clamps. I leave the heater valve and cables and just mask them off.
As far as the motor mount goes, don't magnaflux it as it isn't necessary and
you will magnetize it so that you may never get your compass to work again.
Just visually inspect all the welds, etc. for cracks, have it bead blasted
to strip the the paint and clean any corrosion and then have it powder
coated. A good powder coater can many times do both jobs.
If the plane is a later model Tiger or Cheetah with the all stainless steel
firewall then don't paint it, just clean it and polish it if you want. The
earlier ones were steel that was "aluminized" and may have rusted and
corroded over the years and need to be painted to restore them to good
condition.

Steve, here is how that came about: I took my newly purchased, sadly
neglected Cheetah first to the engine shop, Performance Aero Engines at
Bracket. While the engine was being overhauled, the mount was magnafluxed
and powder coated. The firewall was stripped and painted as well.
Then when I took the airplane to George at Corona for paint, I asked George
to paint the insides of all parts of the cowl in white.
I think he used the same Imron as on the rest of the airplane. In a word, I
don't know.

If it is one with the steel firewall, get some OSPHO from the hardware
store and brush or spray it on. If you spray it, use a good
respirator. Let it sit for a day or two. Lightly sand off all the
black goop and re-apply the OSPHO. Let it dry thoroughly before
painting ..... you can get a self-etching polyurethane primer in white too.

Cliff brings up a good point and reminds me of a rather unpleasant but
funny story, (for another time). If you have them paint the firewall, and
"take off almost everything that can be unbolted readily, like the starter
and master relays," and you happen to include the voltage regulator, make
darn sure they clean off the paint enough so that it gets a good ground when
it is re-installed and then check the charging rate when they do the run-up.

Steve
... Scotchbrite Roloc disks on a Harbor freight angle die grinder are a
"less work" way...
http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=41655
Picture shows the Roloc disks...
If you finish off with the grey "ultra fine" you get quite a polished
finish ... but I would still paint, just go with a tough Imron
paint. Since it's corroding, I presume it's not stainless...:
