I've got a brisket on a UDS built from one of Sterling's old antifreeze drums. I cleaned it with ammonia and scalding water before doing an unseasoned burn, really hot too, it pegged my thermometers and then a burn with the smoker seasoned with lard rendered from pig fat. I work with all kinds of chemicals and don't have any fear of glycol leaching from the steal or anything else. Watch out for old ladies behind the wheels of Fords though. I almost got taken out last week when a woman drove her car up to the counter of a locksmith who I happened to be paying at the time of her arrival. By the way, it wasn't a drive through kind of business before she go there.
