Zinsser Perma White paint

For all of you land lords out there (of which I am one), this paint, Zinsser perma white mildew resistant is excellent. I painted over a glossy Masonite surface in a bathroom with great results. I gave it two coats. Three years later if is holding up strong. I have twice scrubbed down the walls with Fantastic and the paint held up. I now use it regularly between tenants as needed. My lower Franklin St apt came vacant and I painted the floor of the kitchen sink cabinet, and the kitchen drawer bottoms with it. It' got really good stain blocking also.
