Question

The finish or paint has begun to bubble and peal.

Answer 1

a high heat paint,
the paint that was put on at the factory was baked on , probly a powder paint,
at any hardware , high heat paint, also at auto zone, etc.

Answer 2

I would turn the Microwave oven upside down . Scrape the loose paint off and remove as much as will come out.Clean and sand the balance down and feather the edges.Mask the sides so as not to get over spray in areas you do not wish to paint.Apply the high heat paint in thin even coats.allow to dry between coats. continue to build up the coverage to your satisfaction. When you are satisfied with the coverage and turn the Microwave over and remove the masking and you should be ready to use. Good luck
