Gtechniq G5
So, quick review.
Application
Hard work to apply and buff off, Bev called me to tell me id done a rubbish of buffing her passenger window off, which I'd spent ages on. It goes on as a thick liquid and dries to a chalk film, a little does go along way.
Results
WOW! The water beaded off so quick in heavy and light rain I didn't even need to put my wipers on so I don't know if it has created wiper judder or not, so I'll update you on that later.
Summary
Great product if you want a great repellent but not if you want a quick class cleaner.
