I just got my boat back from the shop. The gelcoat was all but gone from the bottom of the hulls, and there was a repair that one of the previous owners had poorly done. The guy fixed virtually all the gouges and scratches, re-did the repair, recoated the bottom of the hulls, and buffed out the whole boat. He charged me $500, and did a magnificent job. I flip flop on what I think if it was a good deal or not. Saved me the trouble of screwing it myself, and probably $150 in material.
