Experiences with GTechniq G4 Glass Polish?

[TheFrankenberry]

So need to take care of waterspots and wipertrails on the windscreen.

- straight distilled white vinegar proved woefully ineffective

- 0000 steel wool works with a massive amount of elbow grease but requires immediate, thorough cleanup lest you want a ton of rust specks showing up in a couple days time

- just applied GTechniq's G4 Nano Glass Polish as directed, with a cotton applicator (by hand), and can only say it took care of some light water spots (not much better than the DWV)


Any suggestions on a more effective application method?
Or another products that works? I've been recommended locally DuraGloss 755 Nu-Glass, MX-7 Ultra (with Ammonium Biflouride?), or any metal polish.

Your thoughts are very much welcomed.

CarPro Ceri Glass is an amazing glass polish if paired with their glass polishing pads!
