I like to paint my own cars. I haven't done a bunch. I have always used high gloss single stage. I'm not the best painter so I end up with some orange peel here and there. I have pretty good luck wet sanding and buffing it out. I have read that buffing a metallic paint can screw it up. I have always done solid color non metallic paints in the past. I would like to paint my next project plum crazy but the paints I'm finding are metallic. I must admit I like the look. So anyone out there with some experience or wisdom I would love to hear from you.
