There was a thread months ago about the merits of Rain X and some other fluid which came in a pink plastic container which looked like a sex aid (I am told ) . Pink stuff much better, gave my last lot away to a mate and find none of local shops now sell it. If anyone has details of maker of the pink stuff, or can point me to a retailer, would be v grateful. Not only is it good on 7 screen but excellent at keeping frost off Golf screen in winter.
