Back when I was a co-owner of a body shop, neither my partner nor I wanted anything to do with a car owner who said "I did my own prep work- - - -all I want you to do is paint it!" We had absolutely NO idea how experienced he was, what sort of mistakes he had covered up with that rattle can primer, or how many times that porous primer had been rained on, touched with greasy hands, or had been subjected to any of at least a dozen potentially disastrous situations before he showed up at our door looking for a cheap paint job. Of course, if the job went sour, that type of customer was more than willing to badmouth our shop to everyone he met! If you find a painter willing to accept your word about how wonderful your prep work has been, you probably deserve the quality of the job you're about to get!
