Roll, then "tip" with a quality brush. Like a Purdy. Depending on the temp, if you thin the paint, use "Penetrol", not paint thinner. Let the paint dry for at least a week, then polish. if you have runs, leave then for a few weeks to harden, and scrape with a single edge razor blade, and polish. That's what I did. If you thin the paint with thinner, you will kill the gloss. The roller puts the paint on the truck in an even coat, the brush is there only to smooth the paint. A light hand is all you need. No masking. No overspray. I used less than a half gallon of paint on my truck. Up in Canada, the paint is $30 a gallon. It looks perfect from ten feet, as you can see, and pretty good up close. No matter what you do though, its all about the surface prep. Sanding, filling, glazing putty. I ended up using a piece of ridgid foam insulation for my sanding block. The trick is to use the Penetrol though, it won't evaporate out of the paint too fast. You do need to work fast to maintain a wet edge though. It took me about 30 minutes per coat of actual painting time. And then you wait.
