A lot of the vinyl hard bottom paints are degraded by exposure to air. Supposedly doesn't take too long for them to be effected when hauled. Give away is if directions call for launch soon after painting. Check with the mfg. Ablative are supposedly Okay.
Does anyone know of a hard bottom paint
that can be used on a hard dinghy
stowed upside down on the foredeck?? An ablative paint
probably wouldn't stand up to the abuse of launching and retrieving and would wear off when rubbed against working up forward.
