Cerakote question

lol, never heard of that one. A toaster is way too hot and you will melt a polymer frame. I have done bake on Cerakote on polymer frames but I don’t go higher than 160 degrees.
 
If it has a convection feature and you can set the temp low enough, it should work fine. Thats an aluminum frame and steel slide, so you shouldn't hurt it at 300deg. Or lower it to 200 and cure for two hrs, instead of one.
