So far, looks like the Bondo Fiberglass resin over Fiberglass cloth is a winner.
We used that several times to repair vettes. Bondo gets heavy if you use a lot of it.
What surprised me was that it hadn't torn at 535 lbs. It did start to slip in the wooden clamps a little, hence the elongated screw holes on the one end.
The Epoxy tore at 455 lbs and the Por 15 a little over 400 lbs. I want to fasten the ends a little more securely and see how much more I can get out of the Bondo resin.
Then again, my scale tops out at 660 lbs, although, I am not sure I'll get there.
The big difference is cost. Epoxy and Por 15 are around $170.00 a gallon, and Bondo is around $70 a gallon.
The Bondo resin is listed as waterproof, although it is also not completely clear like the Epoxy.
Por 15 is not fully clear either, so it depends on the usage.
However, Bondo with Bondo Fiberglass cloth looks pretty good.
