I had a lot of trouble with this last year when I first started using epoxy. I used Clear Coat system three, which is VERY fussy stuff, and it would not adhere to Krylon Clear no matter how much I scuffed and wiped with various solvents. Eventually I quit using a spray clear and put the epoxy directly over the Createx. I handle the plugs with a clean soft cotton rag if I wire them before epoxy and it works OK, though usually I wire afterwards. I also found with the system three Clear Coat stuff that I had to use a scale to mix small batches (syringes apparently have silicone that contaminated the epoxy and cause adhesion issues and measuring spoons gave inconsistent drying results), had to mix with a metal stirrer (wood apparently absorbed the hardener but not the resin changing the ratio in small batches), had to buy a slower spinner motor (18 rpm caused it to flow on handcarves, 3 rpm was better), and use it in a very warm room (over 72 degrees). All in all a nightmare to use and I don't recommend it. I am planning to try a UV activated polyurethane called SunCure next (though I have concerns it may lift the Createx, or yellow too much like other polys). Waterbased clear coats with added "crosslinking" agents are apparently also an option (but I think the crosslinkers are toxic). Something still to be said for rattlecans and spray clears. Good luck.
