Very interesting. I did not try smelling it when I heated it. I tried dissolving it by using some mineral spirits on a cloth to try to wipe it off the spoon I used. Did not come off the spoon. If it is epoxy it is certainly not very hard since I was able to scrape it off with just a fingernail and a tooth pick. I suppose it won't take long to come loose shooting a few rounds of sporting clays?
