Epoxy softens with heat, even J-B Weld - though that stuff has a higher Tg (Glass Transition temp - the point where cured Epoxy transitions from being rigid to rubbery) than most epoxies. J-B likes to say they can withstand up to 550 ℉, and that may be about where the Tg temperature is; they don't exactly publish full specs like an engineering adhesive.
Additionally, Acetone usually attacks cured epoxy, if allowed to soak for 30-60 minutes (along with a lot of other things - including nearly any other finish the body may have).
Those two methods - heat & acetone - are two of the general methods to remove cured Epoxy. That is, of course, if it really is Epoxy.
It may be Polyester resin, which is often used because it's almost as good and cheaper than epoxy. - Acetone will dissolve that too... And nitrile gloves. I seem to recall it shoots through latex with few problems...
Though polypropylene and polyethylene are pretty much impervious to acetone.
