rain repellent on windscreen - do you use it?

[aaronng]

where do u get this autoglym glass polish from? expensive? easy to use?

Autobarn, I think it's about $18-25. Apply on with a foam or cotton pad, work it in and then wipe off with a clean cotton cloth. After you are done, reapply RainX. Oh and don't get the glass polish on the paint or rubber/plastic trim around the windscreen.
