I have a Steelheader pontoon boat. I love it. But, after years of dragging it through rocks, brush and other stuff, I am seeing significant wear on the bottom of the pontoons near where they curve from up from horizontal to the tips. I took mine apart to resew the seams but now see the thread is fine, it’s just that I am wearing holes in the fabric. Have any of you found a way to protect the fabric. I was thinking of something like shoe goo, but thought I would check to see what the combined wisdom of this board had to offer.

Also I have a slow leak in one pontoon. Any ideas on how to find it and what to use to fix it with, if I can find it?
