If you see gel coat you don't have the epoxy, I took the bottom paint off with a magic tool on the 22, when you hit the epoxy it is slick and tough. As in you can gouge it a little but it is not coming off the boat. Either way I would wet sand it down until nice and smooth, then make a decision based on how she looks. I would then have Jason advise on Interlux or vc tar. I have used vc tar several times, really hard, slick, and smooth but prone to sag, the interlux was not as smooth on final finish but easier to work with.
