I used melamine paint to cover some formica countertops in my office. It was very cumbersome to work with. I finally used a small diameter foam roller to spread it. The roller left little bubbles in the surface, but as it dried the bubbles popped and left a little bumpy texture, which actually didn't look too bad. Of course this was on a flat surface ... I'm not sure how it would fare on a vertical surface. I would be a little afraid of it running. There was one little quirk that you should be aware of, which may apply only to the brand I used. This was about 6 years ago and I believe that it was the first melamine paint on the market (I believe the name was "Kyanize"). Anyway, the surface was a nice bright white, but if you placed anything on it for a few days and then removed it there was a yellowed spot where the light did not hit. After a few days uncovered it would be nice and white again. Hopefully they've improved the product since then. It was a fairly hard surface but you could leave an impression with a fingernail edge if you pressed hard.
