For the money, this is the BEST ceramic glass product. It can last 15 cars, and allows you to do all glass for some cars too. Also, my applications have lasted over a year, until they start degrading slightly. I do live in Miami tho, so it rains ALOT.

I tried the G1 and i liked it. Worked well and lasted a long time. Application for this G5 seemed easier so I gave it shot. It works REALLY well for the first week. After that, the water beading/shedding properties are nowhere to be found now :( Pretty disappointed.
