Exhaust cutouts
 

I pulled my exhaust tips off and want to seal the cutouts. What would you suggest sealing with - fiberglass, epoxy, gelcoat, caulk?

Epoxy, then gel coat the surface

The solution is Anti-Bond 2015, which breaks the bond between the adhesive and the substrate, so deck hardware can be removed. Penetration can be encouraged by first scoring the edge of the bond with a blade, which might be required in the case of winches or other hardware that have been in place for years.

thanks.

Here is how I moved my holes, and you could use a hole saw to cut one out and then do the same to seal it back in
