I had some more thoughts about this project that I thought might save some labor. If I were to do it again, I would make the sheathing out of fiberglass instead of aluminum because the aluminum rubs against the fiberglass lower pant and leaves a dark residue. The residue wipes off easily enough with Windex though. I think fiberglass would have been easier to do also since I could have just waxed the pant in the area that I covered with aluminum, applied fiberglass and epoxy, wrapped it all tightly with wax paper or plastic wrap for a smooth finish, remove the cured fiberglass sheath and then cut out the 1" wide section from the pant. It would have made a perfectly fitted sheath for the pant that doesn't leave a dark residue.
