Wait, how did they apply the non-stick part? I see a handheld spray gun for a few seconds. No weird surface prep or heat curing? I'm disappointed. What kind material is that coating made out of?

I don't know but he's probably spraying it on with no breathing protection and it is probably bad to breathe it in.
