How can I prevent a hole from wearing through the stern of my kayak?

There was an earlier thread about this. I followed someone's instructions about using PVC pipe.
You basically heat it and mold it to the shape of the hull. I used some silicon caulking to stuck it on there. We'll see how it lasts.

I put a towel on the ground.. r to here are hill protectors you can get and glue or plastic weld over the spot to protect

Make sure that thing is bonded real good. Last thing anyone need is following someone on the freeway with kayak parts flying all over.
