years ago, one of the head guys at the company that makes 'easy off' was a sailor. he had some 35-40 foot sail boat with [censored] bottom paint on her. he tried a bit on a sample piece and sent it off to the lab to get checked for damage to the laminate. the lab boys said it was fine. the easy off removed all of the anti foul.
this was on a polyester laminate, with a shitty gel coat, not an epoxy matrix.
trust me.
