What did that package consist of? And how would it help regarding the windshield wipers?I have the cold weather package. So that seems to help.
Careful with that stuff. At least in Mk5 VWs, it would clog up the sensor in the windshield washer reservoir...In more recent years I've gone to the Rain-X orange wiper fluid.
I just applied Rain-X, and now I remember the problem with it. The smearing (visible residue) after it's applied. Even after polishing it with paper towels, I could still see the smearing.I find Rain-x smears too much after a while.
So I then I cleaned the windshield with glass cleaner, and that seemed to take care of the smearing. I believe the Rain-X protection is still there. I seem to remember that running the wipers int he rain would get rid of the smearing too, without getting rid of the Rain-X beading effect.
