I looked and unfortunately it doesn't look like I took any pictures, Sorry!
I work at a fiberglass shop so the materials were handy. I wire brushed the top pan and then applied a good coat of honey wax over the top surface to make sure the fiberglass did not stick. Pretty sure I wouldn't of had to do that because it typically will not bond to metal anyway but with the pitting in the metal it wasn't worth the chance. I then took a piece of scrap glass mat and wet it out with catalyzed resin using a paint brush. Once the resin cured I popped it off the seat pan and cut off the excess and ground the edges. From there I sanded down the top surface, cleaned it off, then used spray adhesive on the fiberglass piece and backside of the hose material. Once it tacked up I placed the hose material on the fiberglass. After repeating the process for the second half of the seat (hoes not wide enough) I let it sit for a day to dry. The next day I trimmed the hose material so there was about an inch border around the seat pan and then cut inward every inch or so in order to make tabs that I could tuck under and sandwich between the two metal seat pans when i put it all together. The hose material is not flexible enough to just fold over and tuck in. If I can sneak out into the garage I will take apart the seat and get pictures for you.
