Do-it-yourself paint!
However since it's going to be white, some people make a bigger deal about gaps between panels because then those are the "black" areas and if they are out of whack it could look weird. but 95% of people aren't going to realize it. mainly guys who do painting and stuff like that.
As for the paint, i'm another advocate for PPG. At school we used PPG and Sikkens. I used both to paint different cars, and although Sikkens is known to be a good company, i really didn't like spraying the paint. The PPG just seemed to be easier to work with and flowed a lot easier than the Sikkens.
Just my .02. Good luck with the painting. If you're in there helping, make sure you're at LEAST wearing a half-mask respirator. A full face is much better. (Ask me how i know...)
