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.
