I have an old propane tank that is galvanized on the outside and am thinking of doing a smoker build with it. I am a welder by trade so I'm fully aware of the harmful fumes that galvanized metal can release when heated to certain temps. My question is what would be the best way to remove the galvanized plating from the outside? Just wondering the best way to approach this. Any advise and incite would be much appreciated. Thanks...
