First of all, let me thank you for your advice about tabbing, filetting, and taping the seams. They came out beautifully, and I've so far used about half of the wood flour that came with the kit. Thin fillets certainly save time and money.
I'm at the point now of filling the weave on the C16, and am trying to make a decision about how to protect the bottom from abrasion. I don't particularly like the looks of the dynel strip, and am toying with the idea of a graphite-infused bottom instead. Did you do graphite on your 16LT, and if so, do you have any pictures of the finished product? Also, if I decided to wait until the end of the build for this step, would I simply need to rough up the surface before applying? I guess the benefit of doing it now would be to use the phenolic micro-balloons to save weight and epoxy. Any advice on this would be great, as I'd like to make a decision within the next day or so as to how I'm going to proceed.
