OK, not sure which regulator you have and which one you meant that changes
when you pull the trigger. The regulator I use is on the gun. I can set it
for a pressure and try a pass, adjust up or down a pound or two and try again.
Somewhere between 30-35 seems to work well with the Imron I use.
As for the bubbles being moisture. I hadn't thought about that one. My
problem was due specifically to heat so I'm pre-wired to think that way. Like
Linn said, get a new hose and a good air drier. I use a secondary tank to
slow the air down and let it cool.

They make little tiny regulators that attach directly to the gun and
they're light so you don't know they're there.

Now that's one I hadn't thought of!!! I removed the tube that goes from
the compressor to the tank and replaced it with a coil of copper
tubing. This. at least gives it a chance to cool a little. I have a
long loop of air hose between the tank and the FRL unit that will allow
almost all the moisture to settle out of the air. I purge that loop
every week or so. The filter still collects water! There's also an
automatic purge valve on the tank (Harbor freight .... works good) to
drain the tank. I have "Ts" between each part of the FRL unit so I can
tap air anywhere, depending on my uses. From the FRL I have a hose that
goes over to the paint booth and have a 'toilet paper filter' that's
just outside the booth. The paper filter inside will still get damp!!!
The output of that filter has a small. 1/4" hose that feeds the
regulator at the gun. That's all this hose is used for.I've been using
the HVLP suction gun but am looking at trying the gravity feed type as I
hear they atomize a little better.
I set the compressor regulator to 50 lbs and the gun regulator to 30-35
lbs like Gary does.
Happy painting!!!

Has anyone noticed how much the whole empennage shakes and twists when the
engine in the AA5B comes to a stop? A friend (who flies a Yankee) was
standing alongside my plane ('79 Tiger) when I pulled the mixture and killed the
engine. He was "astounded" by how much motion there was during the last few
prop cycles. He said the horizontal and vertical surfaces shook violently.
I wonder if this could be the mystery force causing the problems recently
found in the tail section of several planes?

Yeah, I've got a Sata regulator at the gun (they call it a micrometer) to
regulate the pressure there. I'll boost the pressure. I have a filter on
the line right before the regulator at the gun, and it is dry. I also
looked up some stuff on the web and think that the extra solvent from the
reducer may have been a contributor. After the paint has flowed out, it
looks really nice, except of course, the little bubbles...
Thanks again,
Steven
