My 1st drum had the clear gold liner. While its one of the easier liners to deal with, it was still a PITA! Now I just buy new unlined ones.
With a new drum......
1. Drill your intake holes.
2. Burn it out good. This removes the paint on the outside, while also removing any oily residue from the manufacturing process. Get it good and hot so that it burns all the paint off.
3. When it cools, wash it.
4. Rattle can the outside with high temp paint. Spray the inside with a light coat of Pam. This will prevent inside from rusting.
Hope this helps!
