Hi everyone. i'm doing my first UDS build this weekend. i bought a new unlined drum. i have a friend who owns a Sandblasting shop so i am going to have him blast the inside and outside of the drum, as well as sandblast an old weber lid while he's at it. My question has to do with the "rust inhibitor" that is sprayed on the inside of the drum(not a lining, just what is sprayed on the inside to prevent rust....still looks like bare metal). if i have the inside and outside sandblasted do i still need to do a burnout or will the sandblasting itself take care of the rust inhibitor? I would think the sandblasting should take care of it but was just looking for some reassurance. Thanks in advance.
