Ok, so a couple years ago i started a UDS. It had the dreaded red liner. I burnt, wire wheeled, sweated, cussed, and finally gave up. Partly because the Craigslist gods opened up and dropped a new 18.5 WSM in my lap for $100. I scrapped that barrel with a smile and have enjoyed my WSM very much.
However, the CL gods parted again and TRIED to drop a new big WSM in my lap for $300. It was a scratch and dent and had a few dings and one particularly ugly one on the rim of the smoker that might have effected lid fit/seal. Then the old lady says its your $$ do what you want but do you really need another smoker? Well...yes, yes i do. So i told her if i didnt buy it i was building one. She said ok, you will get more satisfaction out of that anyway. Shes probably right (darnit).
So, i get another drum from work. Yes red liner again. I burned it out, with a pallet and then some good hardwood firewood, put a leaf blower up to an intake hole and let it run and hit everything with the weed burner...i had every part of that barrel glowing at one point or another during the burn. SOB was HOT.
She cools off and yep, still in there, but this time when i hit it with the pressure washer the red liner actually came off! YES!
Now heres my over thinking question. Its not down to bare metal...but it is close enough that its rusting. There was oil (saddle oil) in it but i looked at the MSDS and its not petrol based, but 2 non-hazardous ingredients, one of which is fish-oil. But i am still wanting it to be cleaner...im paranoid. What do you all say? Season it and cook or go the sand blasting route and be extra safe? I dont have pics yet.
