Hey guys, I need some help here. I have been wanting to make a UDS smoker but have had a hard time getting a barrel. My buddy found a barrel on his job site and grabbed it for me. Can you take a look and let me know if this type of barrel can be used. It looks like it was some kind of water sealant. It only cost me a 6 pack of bud light, so if it cant be used its not a big deal. Any help would be much appreciated.
