Just curious. I recently used it with very satisfying results. I first heard about it on the E30 forums, while trying to find a way to lightly rejuvenate my worn, 17 year-old seats. About a month ago, I made this thread on my home forum: It's been a month, and I am happy to report that the seats still look the same as the above "After" pics, and there has been no discoloration of clothing, etc after the application. I was very thorough with revisiting the seats with a clean microfiber to make sure that all of the residual product was removed, and I honestly couldn't be more satisfied with the result. I think that the seats will bear at least one more application, perhaps more if I feel they need it, and then I will move on to the rear bench. Thanks for checking out the thread.
