Would wet sanding the color coat with 1000 grit paper be wise before spraying on the clear? I'm using dark cranberry dupli color, and while it doesn't say it's metallic, it sure looks it. I've read that you shouldn't sand before the clear, but the surface looks a little rough.

Yeah. I use a semi-hard felt block and razor blade the corner edges off to sand out color coats. I use a real fine grit polishing paper and just enough water to get it cutting without scratching the hell out of it. Nice and level-like.

Hey man, just as it sounds, just CAREFULLY cut the corners off the edges with a standard issue razor blade...even tho it's felt, it can still dig in, and tweak the paper, and I like the paper to float without any chance of gouging if I come at it less than dead flat at first....
