UDS build?

A good burn or two and u should be good to go i dont see where it would be a problem

I just did one with some kind of rust inhibitor (?) sprayed inside. I did 2 burns, then sanded and wire wheeled it, sanded it again, hit it with a torch, washed it twice, sprayed it with cooking oil and it is smoking away as I type this. 15+ hrs, and it looks great. Can't wait to try it.

As long as you get the "leftovers" out, go for it.
