I've been using Gtechniq G1 for the last four years and have always been happy with it. Now that my bottle is depleted, I want to try something else. I dont' see much talk about Opit-Glass and not many youtube videos on it.

How's the beading and durability? Have anybody tried both and can compare? Do the wipers skip when using Opti-Glass on the windshield?

Thanks!
 
I have used opti glass on four cars. It works great. Optimum advertise it will last for 1 year. So far on my daily driver it's still beading after a year and four months. I'm gonna skip a new application of opti glass this year and check the beading next summer.

Application is extremely easy as well.

I have only tried aquapel and rainx which I no longer purchase.
 
I have Opti-Glass coating on my DD, still performing like day 1 after 6 months..
For easy application, don't use the supplied yellow applicator! Optimum dual pro applicator or lake country coating applicator are much better.
 
How many windshield applications from 60cc bottle of Opti-Glass?
 
Just a short and not so good video taken by me some time ago.
