Humidity?

I have sprayed in humidity up to 80 percent with no probluems it just takes a little longer to dry unless you can let it dry in an aircondition room.   ACESES5

Heavily depends on the paint and the temperature going along with that humidity.

I agree, especially about the type of paint.  Lacquer is the worst offender for blushing in high humidity.  But then, hobbyists are using less and less lacquer these days.  Only folks I know who use it much are car guys.  I am talking about real, solvent based lacquers, not acrylic lacquers.  Acrylics in general do not blush from humidity.  Enamel can blush, but it is much less likely than with lacquers, but humidity can affect drying time.

I've honestly never had a problem with lacquers in high humidity - Alclad seems pretty resilient whenever, and Gunze Mr. Color, even though it's kinda-sorta an acrylic lacquer, seems to do well in hot and humid conditions.

My biggest problem paint in hot and humid conditions is Tamiya, which dusts like a ***, even when super-heavily thinned.
