Hi Paul,

I mentioned the epoxy filled with carbide on the board a few days ago. We use to use it for a surface coat while making master molds that had a metal tracer constantly running over them and therefore had to be tough and vitally non wearing. On the plus side this epoxy (Ren Plastics RP-3260 ) was so tough that it would easily destroy a high speed drill bit ( we used tungsten drill bits ) but the wear resistance was unbelievable. It could wear the rocks down before it wore down. On the down side it is an ugly blue (see picture) it is thick and we heated it under lamp to thin it and brushed it on. To smooth out sags or ripples after it is applied is very hard. Sandpaper hardly touches it and wears out quickly. I would say it is 20 time harder then the epoxy plastic we use on our boats. I have not found Ren Plastics on the net but I can get the address if anyone might want to experiment. Meyer Plastics Incs. , 8343 Clinton Park Drive, Ft. Wayne, IN ( also in Indianapolis and I think on the net) is another pattern shop supplier that would probably have something similar, but whether it would have the same amount of carbide in it or not, I don’t know.
