excellent. not the car window it can be used in other devices. even I used it in my mouse when its scroll rolling button slightly stucked.
Very Good Packaging, delivered on time as assured. I used it on the Rubber Piping & other parts and they now work much smoother and no Squeak sound anymore I also received a cool Liqui Moly Key Ring as complimentary Kudos to Liqui Moly & LRL Motors
as described its a perfect product. Cheaper than Amazon.
