Painting: Single Stage now, cover with base coat / clear coat later? I've done a reasonable amount of searching for the answer and info about this, but still I have a few questions unanswered. My questions are: Can I spray a base coat / clear coat over a single stage? Is it best to use a urethane BC/CC if I am spraying over an acrylic urethane SS? I'd like to get some paint on my car to drive it around this coming summer. It's currently just in epoxy primer. I'm thinking of going with single stage acrylic urethane for that. Next winter, I'll take it apart and give it a really nice paint job. With the proper amount of preparation, can I spray over the SS, or am I going to sand off the SS completely before spraying the BC/CC? From what I have read, I think I can rough the surface of the SS, and spray the BC/CC over it. Thank you in advance. .
