With modern paints you shouldn't have any trouble panel painting it. Even metallics these days are pretty safe for this. Now the 3 & 4 stage stuff...
Sikkens is a great paint to work with though. I've been using DuPont Premier lately, and have had good luck with it too. I've also used Diamont with great success... I think as long as you have a good gun, you're OK
