Blushing epoxy

Hey guys,

I sprayed epoxy yesterday evening. I live in Atlanta and the rain and humidity has been non-stop. 155 psi at the wall, 30 psi at the gun. Sharpe 3 stage dessicant system. 45 minute induction time and 45 minutes between coats. Sprayed in a shop, not a booth. After reading up looks like I should have increased induction time and flash time to about an hour each. My question is do I need to sand it and do it again or can I put it out in the sun. This is a hood for a restoration project and I don't want to run into solvent pop later down the road. Car will be going to California. I don't mind sanding again and respraying. Thanks for the replies.

are you painting over it or is it left for everyone to see? if your painting then dont worry about it. it doesnt hurt anything. waiting longer than you did between coats wouldnt do anything to prevent it. its just flashing too fast for the temp and humidity in your area. slow the flash down with some vht reducer.
 
It'll be painted over. I took it to bare metal, applied the 2 coats then will do the filler work next week and top coat it with epoxy before moving to 2k, base and clear. Thanks for the response.
 
Just an update, put the pieces out in the sun for a day and all blushing went away. Going to sun bake them a few days before moving to filler work. Thanks for the help.
 
This can happen with SS, Clear or epoxy, the best way to avoid if you are not in a paint booth with temp control is avoid painting at night.
A good cut off time is 4 to 5:00.
