Stove Bright paint on aluminum?

[7acres]

This is a random off topic question. But I knew this crowd would have an answer for me. I roast my own coffee in a West Bend "The Poppery" hot air popcorn popper from the 80s. The roast chamber is made of cast aluminum and I'm modding it considering a redesign inspired by showing off the innards. I want to use high temp paint on the cast aluminum because the temperature of the aluminum will be in the mid-400s F most of the time when the unit is roasting coffee.

My question is can I use high temp stove paint on aluminum? It says it's for ferrous metals. But will it actually stick to aluminum? Any way to make it work?

Do you really want to chance your coffee tasting like paint?

Good point. But this surface area is outside the roast chamber. Coffee never comes in contact. or even gets mixed with the initial outgassing.

Need to get a self etching primer but not sure if they have high temp ... Had to use this on a bistro chair set with cast iron seat and legs; aluminum backs. Paint will just peel otherwise...

Apparently, stove bright can be used on aluminum BBQs with properly prepared surface ... scuffed and cleaned with acetone. I think the curing of the paint would then be a important element.

Can it be polished like aluminum wheels?

Interesting idea. I'd really have to put some elbow grease into filing smooth some of the flashings. Makes me wonder... Why don't aluminum wheels oxidize? Something in the metallurgy?

I think they usually put a lacquer on them. Maybe not a good idea.

I painted my aluminum firebox on my weber grill and it's been just fine. Scuff it up and wipe it down and paint
