Mates, I need your advise...
Two ears ago my hull was sandblasted up to gel, and 5 coats of epoxy primer was applied before AF. The boat was on water for 2 years without any problems with antifouling.
Now, after lift out and cleaning the boat with pressure cleaner, the hull looks like on a picture - there are many places where antifouling fall off.
Marina guys propose sandblasting again and apply new primer + antifouling, and insist that there is no other good option. I don't like the idea to sand out my 5 layers of epoxy primer, which was quite expensive job to apply.
Is it really no other way to apply new AF on existing epoxy primer?
