I like two part automotive urethane, DuPont Chromabase, is what I currently have. A quart has lasted me years. This stuff is very durable and will stand up to even nitromethane, which will act as a paint stripper for most enamels and lacquers.
I had a warped Satellite body, I emailed them and they replied to run it under hot water. Not the answer I was looking for, especially since I had already tried to repair it. I emailed photos of the body to them and they sent me a new one no charge. Not even shipping.
