I think there was a nail on a piling or something like that in the boats past. Those ones took up to three loads of gelcoat to fill adequately.

You also have to be careful to not sand & polish the touchup completely flush with the surroundings or you get the thin edges you are experiencing. Remember you are dealing with a convex surface so you are ALWAYS sanding a high spot.

SloopJonB,

Trust me, had I not thought that was the way to do it, I never would have

It seemed to be unanimous online that gel coat needs a smooth surface or it will just bridge the gaps and crack easily.

I have some areas like the attached that I would love to fix (they are HIGHLY noticeable, more so than what I just "fixed") but there was no way I was going to try to sand them all out and build them back up again. Can these just be lightly sanded down the middle and then the whole area spread with gel coat? Just don't want it flaking off or something after I've done all the buffing and waxing.

Siamese,

The topsides are actually in great shape. I just need to wash em thoroughly and then follow mainesail's guide (Tips For Compound, Polish & Wax) and I'll be looking brand new! Just didn't want to cut corners so I was going to fill in the dings.
