Hi All, I use blue carpenters chalk but the red would work just as well. I have an oil made from the leaves of a tree in Japan the woodworkers use to coat their tools to prevent corrosion. It does not damage wood, tools, plate or block. I mix chalk and the oil together until I get a nice "paint" consistency. I use a sponge paint brush to brush the mixture onto the plate. I also use a air grinder and a 40 grit sanding disk to take the chalk off the block. No elbow grease and the fit can be as good as you want. That 40 grit eats wood for breakfast!! -- Newton Hunt Highland Park, NJ mailto:nhunt@jagat.com
