My seals all around were a bit dry rotted and the top front targa seal had a chunk missing. This stuff definitely did a great job at rejuvenating the rubber trims. I wish the previous owners treated them. You will notice a nice healthy change.
Thats great! Its mostly for rubber. I put it on all the rubber seals around the car, under hood, door seals, trunk seals, and it does a great job. In theory should help with leakage from rain because it will help the old rubber expand. I also put it on my S2000 convertible top seals. It noticeably helps.
