Hey Rojo,

Weird cuz fiberglass supply shows it in there list of fillers but I could not find it. It is a West System product and the ratio is on the can. You can order it online from Jamestown Distributors, Hamilton Marine, Fisheries supply and others I am sure.

I believe that Steve Putnam ordered it from Fiberglass supply this summer. I believe we just asked them rather than ordering from their product catalog.

Check with your local John Deere dealer they can get it by the quart. Its used on corn planters to reduce friction on the planters internal parts. Possibly cheaper the boat building matieral supplier.

Fisheries Supply or almost any West System dealer will ship it out.   You'll only need a quart, so price differences are fairly minor.

The reason you only need a quart is because the only purpose of graphite additive is to make the bottom black.  (Now if you want to paint all the rocks in the river black with pencil lead that is another story)  Don't believe the fiction that adding graphite to the bottom epoxy makes it slide any easier)

If you add enough graphite to liquid epoxy to thicken it so it can be spread by trowel into a nice coat that fills the fiberglass weave and doesn't run you will end up with a brittle coating that leaves marks every time it touches anything just like a pencil.  So fill the epoxy with silica which yields a much tougher material, and only add a teaspoon or so of graphite per pot to give it a consistent black color.

Too much to learn. Thanks for your thoughts Richard (and everyone else).
