i know this isnt quite on the same level, but i tried 2 car glass products, one is rainx. this stuff is complete sh!te, it smears the glass outside and stops the wipers from working properly, the inside defogging wipes just smear and make the glass foggier?

we did a 50/50
ive also used autoglym glass polish and not a fan, leaves dusty crap everywhere.
i use 1/2 sprays of normal everyday house window cleaner, and buff off with a bit of scrunched up newspaper
