What was on my 52panel rear fenders is just what Denny is talking about. I think I saved a piece of the original but no telling where I put it for "safe" keeping.
I used something else on the rebuild but I've also use the #30 roofing felt a many of times. It also works good on gas tank straps.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
