Painting BC/CC when it is raining outside

S

I've got a paint booth constructed inside my attached garage. The booth has ventilation and filters. I usually paint with the garage doors cracked about a foot.

I've got everything planned to paint BC/CC this weekend but there is rain in the forecast. What should I do? Is there anything I can do to help mitigate the issues?

Is there a particular humidity in the paint booth I should shoot for?

I have a propane heater that I could use to dry the air in the garage. Should I use that?

Thanks,
Sal
 
I know others have stated having problems with humidity but personally I have not. I paint in a homemade booth in my garage with filtered intake air pushing everything out the garage door. (Yes I live on 7 acres in a very rural area.) That being said, I have sprayed base and clear when it was raining outside and the only thing I noticed was less dust in my paint job.

I'll accept a flaming from the professionals now. ;)
 
I will wait to paint when it's raining just because it stays so much cleaner.
Which also proves, against popular belief, that the dust is not coming from me.
Humidity is not a problem for today's paints, it was for yesterdays lacquers, it would blush
but even then a little retarder would solve that.
 
Humidity seems to speed up the dry time, so just use the next step slower hardener and/or reducer. Around here humidity is a constant and it's always raining inside my suit:)
 
Texas you have my sympathies,:) I was born in Galveston and lived in Dickinson until I was 9. I cant imagine painting in that environment on a day in day out basis.
 
My Standox base coat can act a bit like lacquer when temps are cool/moderate and the humidity is high, so we use slow or very slow reducer and extended flash times plus heat when it's called for.
 
for sure you can blush a base or clear but base is more prone to it. #1 use the slowest reducer you can and dont hammer the coats on. longer flash times. high humidity will make clear cure out faster and alot harder than it normally would. universal clear that usually buffs like butter can end up buffing like concrete in the right conditions.
