<p>Try using the Coat It instead, its a little stronger with kevlar mixed added</p>

<p>JC,</p>
<p>Be careful in how much you add to the epoxy, too much will make the epoxy brittle. I had this problem and had to remove a couple layers of epoxy with graphite and the went back and added several more. </p>

Thanks Bennett. It is very encouraging to know the final result works that well. Realized I had a brain cramp, never thinking to look at my vendor (Raka) for guidance. Their website says a tablespoon per 4 oz of epoxy.

<p>Hey Jc, I ended up having to do something like 8 fill coats on my 20 oz triaxial bottom because I was putting it on way too thin. I can't remember the figure, but I put way more powder in the mix than was recommended simply because it wasn't covering like I'd seen on here. The argument is if you mix in too much graphite it makes the bottom softer than a more heavy epoxy mix. Anyway, I regularly launch at a kayak launch where you can't get a trailer closer than 150 yds on a gravel pathway. I…</p>
<p>Hey Jc, I ended up having to do something like 8 fill coats on my 20 oz triaxial bottom because I was putting it on way too thin.

The argument is if you mix in too much graphite it makes the bottom softer than a more heavy epoxy mix. Anyway, I regularly launch at a kayak launch where you can't get a trailer closer than 150 yds on a gravel pathway. I drag the boat down that pathway and the boat just has tiny little scratches in the fill coats as compared to the few on river rock encounters. When installing my drain plugs I used a 36 grit belt sander to make the fitting flush with the bottom and that belt could not cut into the epoxy. So I say all this to say I think I put a few spoon fulls in the bottom total</p>
