I bought a '79 Columbia 29 this spring, and at first the paint looked great, but because we have a dog on board, I wash the boat about once a week. Here it is the middle of August and I have paint peeling all over the place. I am starting to wonder if the previous owner didnt us e a hardner or maybe just slapped cheap house paint on it. Any suggestions on repainting it, cost, and how long it should last?
