OK something about messing with the bottom of my boat freaks me out a bit.

I need to barrier coat and paint my bottom. I've very stupidly had the boat on a mooring for two season at 4 months per season without bottom paint. My boat was trailer sailed for about 20 years so the previous owner never touched the bottom. I for some reason thought Gelcoat and wax was all that was needed. Stupid newbie mistake.

Now I'm terrified of what damage maybe happening to my boat. I know I'm starting to see tiny "pimple" blisters.

How do I know when I've sanded the Gelcoat down far enough to start applying the barrier coat?


Thanks for any advice.

Tim

Pick up a copy of Don Casey's "Hull and Deck Repair" before you proceed. It is $20.00 well spent for any fiberglass boat owner whether you plan on doing any repair/maintanence work or not.
The correct cure for "boat pox" which is what you describe requiers that all the gel coat in the effected area be removed. The area must then be thoroughly dried which can take weeks before the barrier coat is applied.
Get the book!!

Drying the hull out is the key. Haul her during the hottest months and let her sit after sanding the hull. If you can buy or rent a moisture meter and measure the before and after that would help. Most chandleries will know someone who owns a moisture meter and would be willing to help you out (mostly for a small fee) per foot of boat.
