Compound question

OK, I plan on using a Glosscote over a metalic black. My question is...should I compound it before the glosscote, after, of both?

Depends. What is the surface texture of the paint like before the glosscote?

Hi,
I just would to say that you must do some test in some small pieces of plastic to see if the paint have a good reaction......

I'd say leae the metallic paint alone and polish only the clear.
