have a little oxidation on my 30 year old hull so bought some Presta Gelcoat and tried buffing a small spot today. wasn't having much luck and arms were about ready to fall off so spent about 5 minutes wet sanding a small 3' section with 1000 grit then tried the Presta gelcoat again. wow. nice! but i don't want to wet sand the whole boat so might try some Preta super cut then go back over it with the presta gelcoat. either way, it looks better than i thought i could ever get it with just the 30 minutes i spent on it today
