Sure, I took my Boomerang Sprint's top deck to my local auto paint supply store and had them match the yellow paint & put it into a rattle can, then purchased the clear in a rattle can also. I wanted urethane, but was told it's not available in rattle cans. I'm painting in my apartment in NY while the wife & child are at the in laws, so a little pressed for time on my projects. Here's a pic of it before and after buffing. The clear is SEM Promax, it's pretty cheap, about $5. If I was painting a big money composite though, I would just pay for a premium urethane.
hope this helps, Jay
