you got to choose your reducers (thinners) and hardeners carefully.
most companys will have: fast, medium, slow in both.
its how you mix and match them will determine the out come.
at work when its 40+ degrees out side the booths don't cool down after baking. so there sitting at the high 55o-60o wile we are spraying. for this instance id use medium hardener and slow reducer. but it depends on what panels i'm doing will depend on my spraying technique.
sorry for the off topic
