Mine's in Bonavista, Newfoundland
(Canada - East Coast) and I can't seem to find someone there to do the job. Hell, in a port with 40 to 50 commercial fishing
boats you can't buy a gallon of resin.
She will have to wait until I get her to a more proper port to get the job done. But, at 25 years, I think she needs it. I have found a lot of little blisters
with rust underneath. I sand off the paint
, clean up the steel, and recoat with Ameron zink epoxy
top coated with their suggested top coat. I think (hope) I have gotten ahead of the issue until I can get the whole bottom done. I've probably sanded and recoated 20% to 30% of the bottom. It seems it is much worse in some plates than in others. Probably a preparation and/or application issue.
I hope my story works out as well as yours. I know I have some corrosion
in my keel
as it was fitted with a stainless water tank and it was impossible to keep all water out. Last year I got rid of that and now have a flexible Platisimo under a settee plus quite a bit in jugs.
I would be interested in what you chose for a paint system including anti-fouling
