Maaco and Earl Sheib will give you the same crappy paint job. Find a local place that has a good reputation. You do get what you pay for with auto/body places. I've painted a few cars myself. The older paints aren't that hard to use, but the new paints are extremely toxic. Have it done professionally. Expect to spend at least $1000 for a decent job, especially if you expext good prep work, several coats of color, and a clear coat to protect the color. That's the only way to do it right.
I was thinking about painting my hotrod as I build it. I have all the equipment and the experience, but I have decided to have it done by someone else. The new paints are just too toxic.
