On a side note regarding RainX. Anybody know how to completely get that crap off a windshield? Had the car washed in MTL and they put RainX on the windshield, and not even well. GAH! Now the wipers skip and make all sorts of noise.

Have heard of a BMW bulletin stating to use Bon Ami 1886 powder.

Can not find it in Canada. Any other options?
Gtechniq G4 is supposed to be able to get it off. It's used during the prepping stuff anyway. You'll be surprised how much crap is embedded in the glass that even a claybar will miss.
