I used an epoxy stick from canadian tire. You had to use a propane torch to heat the area that was leaking , then use the torch to melt the epoxy and let it drip in place. A pain , but it sealed the leaks.
Beside the Palomar knot another super easy knot to tie, once you've done it a few times, is the San Diego Jam Knot which you can find at www.netknots.com.
