Agreed. I have always used RainX. I have not tried the Griot's product. I think it helps the wipers last longer and be more effective too. Got used to having a polished windshield in western WA/Seattle area, with all the rain, and never looked back.
Does rainx actually market an abrasive glass polish? I thought they just do glass treatments but haven't really paid attention as their silicone based consumer products never lasted very long for me (but at their price point it's not like reapplying is an issue)
I just use the consumer stuff. I cannot say it is an abrasive polish, but it does cause the water to bead up and run will, and help avoid streaking from the wipers, etc. Also, it seems like bug clean up is better with it applied. Started using it when I participated in the Alfa club track days in Seattle, when we drove in the wet as well as dry. Lasts reasonably long for me (re-apply once a month or so maybe, generally less often than that). As I said, I never tried anything else, including the Griot's stuff. first I heard of it was this thread, and I figured it was a lot like RainX. Also, that "polishing" meant doing what regular old RainX does, as opposed to an actual abrasive.
Oh, you worked as a limo driver?
