The once-through raincover was quite blind, the side windows were ok, but no longer new.
After treatment with the A1 Cabrio rear window polish (applied with the Meguiars Even Coat Applicator Pads behalf sponge treated with microfibre cloth) the rain cover and the side windows are like new.
In addition, the interface combines now very smooth and clean.
The polish can be used sparingly and lasts for several applications.
The product I can highly recommend.
