painting

OK my bike got hit a few days ago so I'm gonna have it painted a new color soon. I don't have much $$$ to spend on this so I going to get a paint kit that comes with everyhting I need. Paint, reducer, hardener etc. But my question is about the paint being acrylic enamel. The bike is going to be painted in a garage in about 80 degree weather. A freind says the enamel paint will never completely dry in this hot weather. So I want to know from you guys, can I use enamel paint in hot weather?
