I use system 3 clearcoat epoxy now but I may go back to spraying on a 2 part automotive clear coat paint.
I think you need a 2 part epoxy primer to go over the plug if you seal it after it's warmed and coat it with epoxy. You would get better results I would think in the area of adhesion and compatibility. That kind of primer is not cheap but I need to buy some for the composite plywood/epoxy boat I am about to paint so I will be trying that method of sealing.
I have also tried using pigmants added to clear epoxy for solid 1 color plugs. Seems to work fine and eliminates the painting step. Now I need to test that out on fish.
