The inside of the oldies were made with porcelain. Therefore, with about an hour's worth of effort and a steel wool pad, they can be brought back to original condition. Wayne, you can probably scrub right through the layer of paint you put on. Get some burly steel wool for the first pass, like this: https://www.therestaurantstore.com/items/60227 Good luck!
