Can West System 423 Graphite Powder be used with MAS Epoxie? What mix 10%?

RE: Graphite
Is the graphite just one coat after filling the weave?
How best to fil the weave if you know from the start you are going to have a graphite bottom?
Epoxy only; Lightweight Epoxy and micro- ballon mix; or epoxy and graphite?
What about also adding Colloidal Silica to the graphite for hardness?.

1. No. Ususally 2 or 3 coats, depending on how much graphite you add and how thick the coats are.
2. Epoxy/microballoon mix.
3. Some people do that and think it's great. I never felt the need, probably because I paddle over muddy/sandy bottoms. If it was rocky, I might try it, too. But don't be afraid to experiment.

Yes.
Depends. The more graphite, the slipperier the boat bottom. The less graphite, the harder the boat bottom.
For rocky river bottoms, 10% is good. For sandy river bottoms with occasional rocks and shells, 50% is good.
Pick a value that seems a good match for your paddling area and try it out for a season. Next season, if it didn't work out, it'll be easy to reapply a different mix.
Have fun,
