Good paint for microwave cavity

Have been using this paint for about two years now since the cavity of microwave has continued to loose paint after 12 years of use. Ease to apply, although it take 2-3 coats to really cover the other paint and I now find it needs to be done every year to really keep the cavity looking great. Time needs to be taken to sand the interior of the bad area of the cavity and then apply. I suggest using rubber gloves and cove the arm with plastic bad to keep spray for either area. Also, the smell is pretty heavy after applications, so small fan helps to move this from the kitchen area. 24 or more hours to dry.
