Three years ago I did a did a complete blister repair finishing up with several coats of Interlux
2000e barrier coating followed by ACP 50 ablative bottom paint
I didn't haul the boat for 3 years and the ablative paint
had done what it was supposed to do, which was to wear away and keep the fouling down. Unfortunately because I waited too long to haul the barrier coat was exposed and barnacles
grew on these areas. When the boat was hauled the yard pressure washed the bottom but the base of the barnacles
remained on the barrier coat.
I am trying to figure out how to remove the rest of the barnacles. I don't want to sand the bottom for fear of damaging the barrier coat. Another sailor in the yard said he used a chemical to dissolve the barnacles from the bottom of an inflatable
dingy but does not remember what he used. Does anyone have any ideas for this problem?
