Hello, I got a great deal on a used food grade drum but unfortunately it is still lined. This was the only used drum I could find in my area and it was the right price. Now how do I get the liner off? I've read on these threads people burning it out and other sand blasting. I don't have a sand blaster but I can start a pretty hot brush fire in the country. Would this and maybe a good scrubbing with a metal brush do the trick? Also do you buy the water based rust inhibitor and the Rust-oleum at Lowe's or Home Depot? Sorry, I am new to building things but am dying for a real smoker, so tired of fighting to achieve greatness with not so great equipment!
