If this is not possible, then determine whether it's a hard paint like VC-17, or an ablative like
Interlux BottomKote -- both common freshwater paints. It's pretty easy to tell the difference. Ablative paint will slough off if you rub your hard firmly over the bottom. Hard paints won't (or not very much).
Most ablative paints can be painted over with other ablatives. You can't paint a hard paint over an ablative. My understanding is that you can apply ablative paint over some, but not all, hard paints.
Here's a table that claims to help sort out the various paths:
