Good call on the Rustoleum. When thinned and hardened is some excellent paint for the money. You can even roll it on with a foam roller and it self levels so well that the gloss is fantastic, even better if you color sand and buff. I have also sprayed House of Kolor clear over it with excellent results. Hot Rod actually did an article on painting cars with it last month. It's what I used to paint my whole trailer and I was pretty suprised how well it turned out.
