If you put the badboy in an oven and get it up to 170F, The epoxy should be much softer and it may pe possible to use a sharp push pin to pick at and peal away the epoxy in the areas needed. The HDT of most common epoxies is below 170F. Additionally, most epoxies, even the rapid cure, continue to cure for typically up to 7 days before ultimate tensile strength is reached. Sooner is better than later on any attempt at removal.
