.85oz Plastic Bonder

Since the epoxy was 2-part putty, it was easy get the epoxy to penetrate the PVC pipe in the cut area and get a good seal. It sealed and I have been monitoring the repaired area for almost a month – absolutely no signs any moisture leakage now!

J-B Weld WaterWeld Epoxy

My 1st to use the JB Weld. I have a crack in the side of my Jon boat where the corner of the seat punch a hole. Even though it was above the water line it was recommended by others to use JB Weld. That is what I did. No problems as yet.
