As you can see, I got the factory seat out and now have finished cleaning up the inside of the hull where the seat pan meets the boat. The pan, which is made of a nice thick piece of molded plastic (Kydex?), was originally stuck to the bottom of the cockpit with what looks to be a really strong silicone cement.
The glue fastened really well to the Kevlar but did not seem to adhere at all to the pan so over time the pan broke loose from the glue and managed to rub the topcoat of epoxy away from the fibers. I am going to re-seal that entire area now that I have it cleaned up and install a thin piece of minicell between the pan and the hull hoping that will keep it from rubbing.
