I have a 1979 Globe 38, which is going under major refit. I have had to remove some of the deck planking. (teak over fiberglass) The original deck plugs have a flexible gel-epoxy over the screw heads. It can be coaxed out without damaging the plug hole. The ones that have epoxy over the screw heads are nearly impossible to extract the screw without messing up the deck plank. Anyone have any idea on what I can use.
