Not worth it
April 25, 2015
I put it on 2 different windshields. One was prepped with a Nanoskin Autoscrub pad and ceriglass, the other was a brand new windshield. G1/G2 is 100 times harder to put on (especially the prep method) and 100 times more expensive than simple RainX. It works no better and lasts only 2-3 times longer.
You're welcome to come get my remaining product if you want to try it.
