rather spray runs than spraying litlle paint-..........runs can be sanded down.
if you are going to learn the thecniques of spraying. you need to be wery patience. you need to get a common sense of what is happening with the paint when you aplly it, and you need to be clean with every thing you do. have seen a lot of good work be destroyed because the painter has been dirty, if you understand? my english writing sucks heheh i`we been a car painter for 13 years. and still learning new things. .. the best word i can give to you is that you dont give up. no matter how many times you fail.. learn from your mistakes and take time to try too understand whats happening.. if you by a good book you will get the basic information qabout it. but the experience you will need to learn self.

hope that was in any help too you. and that you understand what im trying too say,without any mistakes.as i said my english writing sucks
