Sir,

Painting is an art - tricky and hard to do. The safety equipment is important. I would take your model to a small local auto shop, meet the boss and ask them to shoot it with a coat or two of thinned clear. They clear everything these days. They always have a little extra in the gun, because they can't run short on a job. If you offer them $300 in cash, ans can wait about two weeks you will have a much better result than trying this your self.
