I've had good luck using a local body shop. The guy that painted it was kind of excited about doing it and went nuts when I brought it back in finished. He charged me $150.00 and was only supposed to put on the main color but ended up by doing a little finish work thewn after the main color, threw on a clear-coat for me and baked the finish.
Dean Wrges at Specialty Auto Body in the St. Loius area is one of the top boat painters around but he isn't cheap. His prices start at $275.00 plus return shipping for a very basic paint job but Dean can't do anything simple as he has to add subtle things to add a little extra bling to them. He does all of the show boats for Aeromarine and the pix in their ads don't do the boats justice. He's also done custom bikes that have graced the covers of almost every biker magazine.
It's just a matter of how much that you want to spend.
