New build reverse flow smoker

[NSBBQ]

I recently had a friend build me a reverse flow smoker on a trailer out of an old 80 gal compressor. My question is do I need to grind the inside to bare metal prior to seasoning it? It is rusty but not flaky rust. I have had a fire through it already.

My guess would be no. As long as it not flaky and will not fall off on your food as you are cooking.

Could you power wash it to remove anything that will release and then oil it and start your seasoning burns?
