Well, I am going to start right and post a hello in the Roll Call. I went to the local propane shop to inquire about an old tank that I might be able to use as a new smoker project and the guy told me that the scenting agent that is used in propane gas would have permeated the metal and would make the food taste like propane. I cannot believe that everybody that uses old propane tanks had that problem. I just figured that guy didn't know what he was talking about. This is going to be my first smoker so I am in the research phase. Is there really a problem with the propane scenting agents? Should I try to find an old compressor tank instead? I see lots of pics of converted propane tanks so unless there is a special preparation process, I think it is ok. Anyway, I love this board. Thanks.
