I was able to locate a food grade drum. $135 delivered to my house. It had apple syrup in it, but the syrup was in a plastic bag. The guy I called said it was 'food grade', but that it would need to be burned out. Can I burn it out in my backyard without generating a bunch of smoke and fumes for my neighbors? How hard is it to paint the outside? Do I have to sand it down or anything? Is this a good deal?
