Haaaa no man, I work in a plastic sheet factory but there is an area that I can paint in that has no air flow. I use rustoleum or auto paint. I will be using a metallic black with some small blue metallic flakes in it from when I had to touch up my subaru last year. I think it'll look awesome. Yes, ALWAYS sand before you paint.
Ahh, I see. I think it'll look awesome with your choice of paint. Good luck man. Make sure to post high quality pics with good lighting when you're done.
