‘Rubber’ Seals
The seals on most vehicles are no longer made of natural rubber; vehicle manufacturers use a specialized synthetic material called ethylene propylene diene monomer (EPDM). Real rubber, or blends containing real rubber, just cannot endure the direct exposure to sunlight (ultraviolet light) and the harmful-to-rubber oxidizing gases in our atmosphere.
The soft seals around doors, windows, and sunroof’s hood and trunk are constantly subjected to thermal flex and compressed all the while being subjected to a hostile environment. To remain functional, they must stay flexible and require protection from the environment. The surfaces can be cleaned using a damp micro fibre towel and Iz einszett 'Plastik-Reiniger' Door and window seals must be treated 3-4 times a year.
