Solar Cover Repair

I've got one of those solar covers and a seam or two is starting to tear. I've inherited this cover from the previous owner and I'm trying to get as much life out of it as possible. I'm fairly certain that I can get at least one more season.

Is there any tape or anything out there that I can use to help keep this cover alive?

Gorilla tape works great. We cut our cover in sections to make it easier to put on/take off and taped all the cut seams with it. It stands up to the water and sun exposure very well.
