Okay, now that I have the boat turned over, I can see that the light blue hull has these white scuff marks all over the bottom. How do I get rid of these? Is there a way to buff them out? I want to wash and wax this hull, so what products do you all use? I also noticed a slight crack in the gelcoat on the corner of the slot where the dagger board slides out from. I have these random cracks on the deck and inside the cockpit as well. I'm including some photos. One is a photo of the scuff marks, the other photo is the gelcoat crack.
