Sanding and filing the cured seams

Above is a seam that has finished curing but hasn't been cleaned yet. First we used a razor knife to cut the excess fiberglass tape off the edges. A lot of the epoxy had splooged out on the side where I couldn't clean it up with a squeegee. On the first seams (which were super messy and uneven) I tried to use the razor knife to get all the epoxy off, not just the tape. I found it much easier to shave the cured epoxy with the knife just a little bit and then use a file/rasp to grind off the rest so that it is flush with the wood. We found a 4 in 1 file/rasp at the hardware store that has 2 different rasps and 2 different files all on one. It works really well. Kelly used a straight razor blade to scrape the epoxy off and then 60 grit sandpaper to finish it. Both worked pretty well.

We also sanded down the face of the panel to make the transition from normal wood to epoxied seam smooth. Since I did such a poor job of squeegeeing the first set of seams I had to use a rasp first to grind off all the epoxy then 60 grit sandpaper to finish it. Below is a pretty finished seam.

Also just to note that we let the epoxy cure overnight after each set of seams and there are 8 sets of seams so it took about 8 days to do this first section.
