House of Kolor's KP2CF, and SPI's epoxy are both a sandable epoxy (may be other's that I'm not aware of) Where they aren't quite as easy in sanding as a high build, you are able to sand with no loading. I think the only time I've seen loading of the paper was when the EP needed to cure another day. For all of the motorcycle paint jobs I've done, I didn't use any slick sand or high build. All of the build was done with H/K KP2cf, all wet sanded with good results.
