The filler I used is PC7, this stuff is great for plastic repairs. It was part of the Eastwood kit. The SEM paint although, wasn't so great.....My friend who refinishes antique bathtubs, sinks, and urinals swears by this acrylic coating. He says it will never chip or scratch, a couple coats of clear for extra protection. I noticed that the pictures look as if the finished surface is rough, that is not the case, smooth as glass!
