Thanks so much!!! I got a small microwave from a rental unit ( it was rusted ans I thought i would be excellent for my fishing cabin ( in the wine country ). I WANTED TO USE EPOXY OR ENGINE PAINT!!! The mention set so many individuals at multiple sites off to saying things about toxic fumes and other ridiculous things. there’s even a special paint Amazon sells!!!
