I've been using this product for a while. We originally got it for all the seals in the convertible top of our BMW, but it's definitely brought life back to the door seals in our XJ and TJs. I'm not saying it'll repair cracks/tears but it will soften the rubber and swell it slightly allowing for a better seal. It's not oily, applies with the foam applicator, and a little bottle goes a long way. I think we picked it up from Amazon but can't remember for sure. Just thought I'd post up on it since I think it's an awesome product!
