Patching a convertible top?

Mine is torn is a similar spot. I used something called Tear Aid. There are two types, an "A" and a "B". Don't remember which one I but the package said which one was for vinyl. I think I bought it at Bass Pro Shops. It's been on there a year, but I've only run the top up and down a few times (Fall, Spring and Fall again) since I've done it.
