Rebuilding a Smoker After Massive Grease Fire

I had a pit Boss go nuclear for about 10 mins before I got to it. Flames looked like the post earlier today. I put the smoker aside out of my frustration for trying to cook another brisket before I deep cleaned it and a few months went by…. Things started rusting over where the paint burned off. Would love to hear from you all on my plan to rebuild…. Wire brushed all the rust and loose paint away.

• Wire brushed all the rust and loose paint away including all the loose powder coat INSIDE the smoker.
• High temp black paint on the outside
• Any cooking area inside (see the inside of the lid) I'm not painting since that's in the cooking envelope. Figure I'll put come veggie oil on it and fire the smoker up a couple hours and do a test run making sure the wiring/brains still work well and use the time to season the raw metal with oil inside the smoker.
• Re-install the grates, throw a Costco brisket inside and send it!
