So my brother mentioned that he wanted to paint some parts underneath the hood. His car's engine bay is in perfect condition. There isnt a drop of oil anywhere, nothing, spotless. So I want this paint job to be done properly and to hold up. So I was wondering what is the best way to paint the metal and plastic parts underneath the hood? Also, many people stress that the spray clear coat is not good. How much would it cost to take the parts to a shop and have them clear coat it? Any and all advice is welcomed. Thanx guys.
