I have a 14' Mitchcraft open tri hull skiff built in 1984. It was trailed all of its life and now will be kept in the water 9 months every year in the Chesapeake Bay. The boat was put in the water for a few weeks in late winter without bottom paint and pulled out to discover that small (pin head to pea size) blisters were ocurring below the water line. There are also some pin head size blisters above the water line.
The boat being all scraped up is in need of a paint. So I let it sun dry for the past 3 months, the blisters below the water line bleed out some sticky tar like goop from cracks in the gellcoat (small amounts... just a drop or so).
I went ahead and washed it with a pressure washer then sanded the entire hull (above and below the water line). Only a few blisters were sanded thru to raw glass. Some repair work was done to keel as it was scrapped down to raw glass from beaching it and delaminated rub rails from hitting a dock. Repairs were made with West system epoxy, and the chips and dings filled with West System with flairing additive.
That is where I am at right now and want to get the boat back in the water. I have no itent to make cosmeticly perfect, as it is just a basic fishing and crabbing skiff.
I am throughly confused after reaserching the web on what to paint the boat with and the use of a barrier coat. I was considering an epoxy barrier coat and then a epoxy paint job and bottom paint. A local boat repair man advised me to roll the entire hull with 3-5 coats of colored vinylester as it is more flexable if the blisters beging to reocurr and is quite durable.
Any suggestions on my best way to conclude the job, keeping in mind the boat does not need to be cosmeticly great.
