Hi, I added graphite (and collidal scilica -- West Systems stuff) to the epoxy used on the bottom (below the waterline) on my cedar strip canoe. This does seem to create a more scratch resistant surface. Also this coat does not need to be protected from the sun and water like the plain epoxy (which clouds up). These were the reasons why I tried it. I have been using this canoe for about 5 years and am glad that I took this approach. If I had varnished the bottom I would be constantly touching it up due to scratches from rocks. I don't really have to worry much about sliding over rocks in rivers (or those in the BWCA where they hide in that dark water). Since it is below the water line you don't notice it except when the canoe is on the car. I don't know how "low resistance" it is (is that the resistance against the rocks or the water?).
