The shop I went to was in San Marcos, and they seem kinda shady. They did an OK job on my bumper, nothing spectacular, but I saw some of their other work there and it wasn't that great. I forget the name of the place, my friend got me a hookup there so I took it. In San Diego, try Amato's, I always hear good things about them.
