I did the inside of the cabinets with a white enamel, after cleaning well with first a solution of bleach and TSP (tri-sodium phosphate). The problem I experienced was the enamel flowed into the 'dents' in the ensolite surface at the expense of the ridges. The ridges appear to have only a very thin coat, where the dimples seem to be much whiter.
It took a second and third application to coat the ridges sufficiently. However I'm not entirely excited about applying that much paint to the whole interior of the coach.
Looking at the Zinzer website mentioned in Lisbeth's post above, I think that may be a winner. The three factors I like about it are 1) mildew proof, 2) flexibility and 3) adherance to even glossy undercoats. A fourth is that it is water based. The fumes from the enamel drying are not nice, even with all the windows
open and a 20 inch box fan blowing in the door.
I checked on availability in my area and there are several local places that carry it, so I think I'll just saunter over and check it out, especially if it's a rainy day. It always seems such a waste to spend time shopping when the sun is shining.
