The only paintjob I have done using Krylon was a hummer body my brother in law trashed so bad I couldn't even strip it and redo it. He was going to throw it away so I figured I would experiment with it. I masked the windows on both sides, then spray painted it with Krylon ultra flat black paint. I wanted a flat black primer look to it. I worked great, the ultra flat stays flexable once dried, and if it starts to look crappy, mask it off and hit it with a new coat, then it looks brand new. Since it is also black on the inside when it gets scratched it is no more noticable than a regular paint job. I was surprised how well it adhered to the lexan, I forgot to mask one window on the inside and had a hell of a time stripping it off. It's a great look for that flat primer look and worked very well.
