I have a tarp that has been over a roof since January, and many "on and off", "on and off", "on and off" combined with many hours of sunlight have made it no longer watertight. I would prefer not to buy a new one because I have put a number of eyelets in it so that it sits properly when it’s windy - otherwise that would have been the obvious choice.
Now I am looking for some kind of "compound" or similar that can be applied. Do you have any ideas? Tar gets so damn sticky when it has to be on and off. Some kind of rubber compound or similar would be perfect.

This might work but it requires such enormous amounts: LINK
