I have a very old GRP trailer sailer. I have applied A/f for 36 years. However recent years antifoul paint seems to have a habit of disappearing exposing patches of gel coat after a few months. Using a fairly cheap A/F made I think in Malaysia. I wonder if I should prime the affected areas. So I looked at Primacon and found it recommended for all surfaces but not GRP. Am I missing something. Any ideas. yes I do in water scrub fairly vigorously and frequently but I don't think that is the cause of paint loss. ol'will
