Original BMW Gummipfelge rubber care gel. This special compound ensures no squeaking of door rubber seals on BMW cars or any other non BMW car (specially recommended for convertibles). It also helps to keep your rubber pipes in engine bay soft and flexible (as we all know they tend to become brittle over years if not using this stuff). I have used this on my BMW E46 convertible which had squeaking door seals and it fixed the problem.
This is an brand new Original BMW product in 250 ml bottle.
Using: Apply to the rubber part with a soft cloth.
