Unless you really know that end of the business, I wouldn't get to hung up on the processes the shop uses, but rather the end product. Ask for references from several of their customers and ask to see their cars and paint job and to talk to them. Most shops will be more than happy to have you talk to a previous satisfied customer. Of course, if their not willing or have no references, it's probably a good sign to move on to another shop.
