Seeing your post inspired me to give it a go. Two liners, 60' of fiberglass reinforced tape, and an hour later I was done. I only taped a single side, with reinforcements backing the seam joining the two liners and at all the grommets.
It looks really good, but I haven't gotten to try it yet. Hopefully soon. Has anyone gotten to test it in the wind and/or rain yet? nm I see its done well in wind and rain.
