Sorry about the tear, I know ya gotta be sick over it. I helped a neighbor with his tear (it was a lot bigger than 4"). He bought a liquid rubber and the eternabond from an RV supply place in North Carolina I applied both. Liquid rubber over the actual tear, the eternabond over that and another coat of the liquid rubber. It may have been overkill but it worked great and no leaks. GOOD LUCK
