I have my cab ready to for paint. It has been repaired, primed and sanded and is literally ready to spray finish paint onto. I have single stage Urethane paint, and I'm interested in knowing if it is OK to apply it in this hot weather. It's going to start out each day this week in the low 70s, but will rise into the 90s by mid afternoon. I definately would not paint at the hot point of the day. My question is: would it be OK to paint with the temp in the 70s, knowing that it will get much hotter before the paint is cured?
