I need a short-term fix for my glass.
Long term I'll be having a crack at using G1 but in the meantime are there any general products I can use or should I just give it a good wipe with a MF cloth during the drying stage and leave it at that?
Gtechniq just released C2V3 and it's very good on all parts of the car. Very good on glass, even use to clean it whilst you're there.
Windscreen nothing will last because of the wipers sadly. G1 and nanolex ultra are the only wiper-proof sealants i've encountered so far.
