The paint jobber can be your biggest asset or your biggest nightmare. If the people don't understand the paint technology how can they help. It's a good idea to spend at least as much time finding a qualified paint jobber as it is to pick a paint brand. Paint is paint and they are all made to work. Granted, some may have a better primmer or a more forgiving base and a better clear but like i said "paint is paint", it's the people behind the paint that need to be their for you when a problem arises.
