Review on Nextzett 91480815 Gummi Pflege Rubber by Eric Rios

I used this for the rubber seals on my Volkswagen EOS and was really surprised at how well it worked. On a rainy day I had a leaky seal just above the driver's seat and smeared all the seals with rubber conditioner. It was easy and there was still enough left in one of the bottles. Two days ago I drove home in a pouring rain and there was not a single leak! Excellent material!
