Is there a product to 'feed' the numerous rubber suspension & drivtrain parts that seem to dry & crack. I once heard that Germany is not famous for their rubber quality, which may explain
at least some of the leaking problems that have been posted. I've been using a Meguire's product on the window gaskets hoping to avoid leak there. And then there's the door gaskets etc. etc. The more you look the more rubber you find!
