Recently cleaned off the old bottom paint from my M17. Got down to the gelcoat which had a waxy sheen to it. Lightly sanded the sheen and applied two coats of bottom paint directly to the gelcoat. The boat is 35 years old plus, had no sign of 2000e barrier coat and had no evidence of blistering. Am I in trouble for not applying a coat of 2000e before the bottom paint? My plan was to use the boat off the trailer with the hull being wet for no longer than a week at a time and mostly day sailing. If I do decide to moor the boat at a marina though would blistering become a problem? I had an M17 back in early 1980's which was a 1974 model and that did not show any signs of blistering either even though I had it at a marina for over a year at a time. Tom B, M17, "AS IS"
