Dan-
I just looked for at least one of my two manuals, but couldn't find
either...one is at the hangar...I'm almost absolutely positive that
the figure is 70%. I seem to recall that it says something to the
effect that "if it's over 70% humidity, find something else to do".
I know that when I painted my plane, I measured humidity and avoided
anything over 70%, and when I absolutely needed to finish a coat or
whatever, I'd bring in the dehumidifier....my paint "booth" was about
8' x 8' x 24', so it didn't take long to bring it down. On the other
hand, I sometimes needed to wet the floor to bring it up to avoid
static electricity. I hung a length of copper braid from the metal
parts down to the floor to ground out any static build-up. You may
laugh, but I actually stuck a length of copper braid inside my sock,
and out onto the floor so I didn't get a poke when I walked around
and touched the metal parts. Such is painting in Michigan in the
Spring.
You could also use a blush retarder...Poly Fiber BR-8600....which
says on the can to "slow down the drying time." I seem to recall that
if the paint dries to fast, the humidity in the air will cause the
paint to "blush", which is the humidity showing up on the paint
surface. I can't recall all this from memory, and always look it up
just before I actually paint.
