Hi, I have been told that MAKO does a nice job painting because they are consistantly doing it and as you may know, constantly using a spray gun inproves your ability.
The quality of a paint job is determined by the prep work, not the spraying of the paint.
The best spray-gun person on the planet isn't going to make a dent go away by spraying paint on it, or get paint to stick to a dirty surface.
But I do agree with everything else in your reply... go for it!
