This was an ongoing review that I never posted here, so this post will be many condensed into one. I won these products in a giveaway on AG's sister forum.

First up, the bottles:
You also get applicator pads and a sticker. Please note that it appears that you get about 20 applicators, but in fact there are only 4 or 5 I believe. They are thick, do NOT try to pull them apart otherwise they will lint.
The car was already sealed with Adam's Quick Sealant, but that was easily removed by Adam's APC as well as IPA. Next would be to clay and polish your glass (preferably with G4) but I did not do this as it was thoroughly cleaned about a week ago, so today was just a good cleaning and surface prep.
I then made sure everything was streak free using an Adam's Glass towel.
GTechniq recommends 3 layers of G1 on the windshield and 1 layer everywhere else. I only did the windshield and used 3 coats.
Here it is immediately after application:
Here it is 15 minutes after application and ready to be removed:
To remove, take a clean applicator and apply G2 residue remover. Now, here's the tricky part, once you put G2 to the windshield, you must immediately remove it otherwise G1 residue will still be left behind. To do this, I put a G2 covered applicator in my left hand, a short loop microfiber in my right hand, and then proceeded down the windshield so that my microfiber immediately followed the G2 applicator.
It's a bit tedious, but not that difficult. Here is the clean and coated windshield:
As far as its performance and durability, I will have to report back after it rains or I wash the car. I plan to update this thread until the coating is gone.
As with all coatings, work in a well ventilated area and wear PPE. Also, the bottles could be improved with some sort of dripping dispenser like CQuartz has instead of just an open top. I used 7-8 mL of each bottle, so 15 mL should be just enough for one car.

It finally rained, so time for an update.
After sitting through an overnight rain, here is what the windshield looked like in the morning.
For comparison, here is what the beads looked like on CQuartz:
When I drove the car, 34 MPH seemed to be the magic speed that made the beads fly up and off of the windshield and I must say, at a very rapid pace.
Here it is after a much heavier rain:
The product beads great, but then comes it partial downfall. However, all sealants and coatings have this issue that I have tested.
It provides very little help for the water spray kicked up by the other cars on the road. There is no movement of the water spray on the windshield until about 50 MPH and even then, the droplets are so small, they don't clear the windshield like the larger beads do.
In summary, G1 performs better than others for large beads as pictured above, but only performs similarly for light rain that causes small beads and water spray kicked up by other cars.
What would make G1 impressive though is if its durability claims hold true, and if so, I'll be updating this thread for a while.

3 week update:
I am a bit lost for words because it's performing really well and badly at the same time. The product still beads fantastically making it easy to see in the rain, but even at 55 MPH, the rain beads had just started to move up the windshield at a very slow rate, which is over 20 MPH higher than the previous bench mark for water movement.

It rained again today and I have to say I was pretty disappointed. The performance was even worse. The coating is still there, but it's not effective enough to be useful on the windshield. It would probably be great on the side windows, but the windshield not really. It performed great a few days after application, but now I think I'll be removing it in favor of another product.
* A Gtechniq representative did mention "Also, try to use a clean terry cloth or lint free paper towels when removing the residue with G2. Microfibers may pull too much of the product back off the windows." However, I would like to note that the directions do not indicate what type of towel is recommend. Perhaps, product was pulled off of the windshield, but there is really no way to tell. However, the performance was great initially, so I would think that the coating did indeed bond and did not get pulled off.
