A way to fix non-skid on the newer boats?

[muddywater]

From the posts I have read, it sounds like most people are using paint-on non-skid or spray in liners. Does anyone know if there is a way to spot repair the diamond pattern non-skid surface on the newer boats in places where holes had been drilled previously? Also, if you did gel coat over it, is it even possible to polish it?

Thanks
