So I dug through the garage for some sheet metal to build an extension on top of my kettle to better use it as a smoker.
Unfortunately, I have only galvanized sheet metal.
I've read that the heat from the smoker won't get hot enough to release the zinc coating, but I'm skeptical.
Lowes sells sheets of aluminum, but I think that is also coated with something.
Any thoughts? Is galvanized a super-bad idea? Is aluminum just as bad?
I can probably find some sheet metal that's not coated, but not in my garage (I have some stainless, but I think it's very thin and I stashed it way up in the rafters and buried it under a bunch of other junk last summer).
