kayak leak

[N Florida Mike]

Anyone know something good to fix a tiny crack in a kayak? I tried some kind of marine bondo but the bondo kept sticking to the knife more than the crack.

Thanks,Mike

I own one of these KC Welders and fixed a few kayaks that had one too many encounters with rocks on the Potomac River. One has been on the water for 5 years since the repair with no further issues.

The trick to using one of these is to really allow the polyethylene on the kayak and the rod stock to get gooey soft so that it mixes together. On a couple I actually buried a small sheet of wire mesh into the polyethylene to beef up the area.

You can also do it this way:
