Review on Nextzett 91480815 Gummi Pflege Rubber by Rodney Gonzalez

I've been using this rubber care for 11 years now. We have a BMW E93 with a hard top and lots of rubber seals and panels. Twice a year I go through all the trim under the hood, deck lid, door jambs and hard top. This really keeps the fillings from drying out. I started using this on my Ford F-350 which is about 15 years old. Rubber seals and exterior window seals brought back to life. My only criticism of using this product in the past has been that the foam applicator kept jumping off the bottle and I ended up applying it with a different sponge material. On this last order, they've either improved the applicator or I'm applying it carefully. If NEXTZETT ever reads these reviews I would like to know if they improve the app. Otherwise I like the liquid product and will continue to use it for convertible top seals.
