I was able to get a barrel to use as a pre-burn barrel. It will not be used for smoking. It originally had one part of a two part water based epoxy in it. I am assuming that whatever was in it was not good to eat. The barrel also has a coating inside. If I wash the barrel thoroughly and run a fire or two through the barrel, should it be OK to use to pre burn wood for mys smoker? If not is there any way to make this barrel clean enough to use for this purpose?
