another possible soulution that ive been told is that a heat gun applied to the epoxy will make it gooey and melt it, im sure its not good for covering but can't have everything...
I would bet that the guy who told you that didn't think to mention how much heat it takes to soften the epoxy. It takes a lot. Some epoxies don't go soft until they start to char (burn). A number of them can't be defeated by a covering heat gun.
And for the most part, the heat doesn't melt the epoxy as most of us define "melt". Most things that melt will "freeze" back.
