I've just had my new CT200h delivered last week, and had it Glasscoated prior to delivery.
A mate also had a CT200h delivered on 1st March, and we were comparing the cars, and the difference in the finish between his, and mine.
Mine is TONS smoother!
I've had Gen-3 Glasscoat on my previous cars - volvo, audi, VW and without exception when I've come to sell them privately every single buyer has said how fantastic the paintwork looked. And I kept them for 2-3 years each, and washed them not very often.
The difference between all these paint protection products (and there are loads out there) is that the Gen-3 stuff is not a polymer or wax based product, so it won't wash off, no matter what I do to it. Also it doesn't need to be topped up or anything, and I can put it through the carwash (cos I'm too lazy to do it myself!)
Anyway, the upshot is that I think its great stuff and would recommend it to anyone!
