<p>thanks for the input on the durable bottom finish,I'm just getting back into working on the boat from a long winter here in Wisconsin. next step is glassing the bottom and was just looking for other than just graphite in the top coats,just bought some 404.</p>

<p>Epoxy by itself is not very tough,put some on a piece of ply let cure add some weights on top and drag it down a gravel road behind your truck.The epoxy will be gone in a short distance.What makes it tougher or harder to sand is dense fillers like West 404 high density filler.</p>
<p>Graphite by nature is slippery but not very durable so we wet out our glass with epoxy when tacky we fill the weave with a thickened mix thats hard to sand this fills the weave so you get a flat smooth surface…</p>

<p>Graphite by nature is slippery but not very durable so we wet out our glass with epoxy when tacky we fill the weave with a thickened mix thats hard to sand this fills the weave so you get a flat smooth surface then paint on a couple of coats of graphite.So you get a nice shinny black bottom thats slippery and tough.Repairs are easy because the graphite isn't in the glass its on top.</p> A combination of both, triaxi…tag:woodenboatpeople.org,2017-04-20:1312281:Comment:1447312017-04-20T00:46:24.972ZRick Newmanhttp://woodenboatpeople.org/profile/RickNewman
<p>A combination of both, triaxial cloth with epoxy for abrasion resistance, graphite may or may not slide easily on rocks.</p>
<p>What I have found is my boat built with these components does slide over rocks and I can observe scratches in the graphite, most of which are very shallow. Since there is water pushing on my boat I don't have a method to discern whether or not there is less friction than without graphite.</p>

<p>I did suffer a broken out chunk of fiberglass, epoxy and graphite along / behind one of the chine caps. Obviously a hit on a rock probably suffered while traveling with my boat perpendicular to the current.</p>
<p>Repair was easy, mixed a small batch of epoxy, slathered it in and let it cure. The river will sand it flat. You could choose to add graphite if desired.</p>
