I read everywhere that if I want to put a clear coat over utrethane paint, I have to do this in a few hours before the urethane paint becomes too dry. Otherwise there will be no chemical reaction between coats, what causes poor clear coat adhesion.
I also read that acrylic paint has no time limitations for clear coating, and I can put the CC over it whenever I want to.
However, there will be no chemical reaction between acrylic and clear coat (or indeed?) as well as overdried urethane! So what's the difference?
I'm using PPG urethane colors at the moment and I'm worried about poor CC adhesion in the future, because my airbrush painting process takes time and the clear coat is applied in a third party workshop (more time lost).
I'am at very begining, and wondering which way to chose. What is you experience in terms of automotive painting? Is the time issue important in airbrushing? How to solve it if it really is?
