Hey there, my first post here!
I have been researching a lot about glass and windshield coatings since my current ceramic coating provider offer one that lasts less than 6 months for windshields so that is a big problem when you have customers paying a lot for lasting protections so had the task to find other options. Here are the best consumer available options i have found:
PBL Diamong glass coating seems a good one and the fact that you can protect up to 50 windshields with just one bottle makes it very profitable, but is not an option for what i am looking for; i have been reading some reviews and some people stated lasting less than a few months because of the wipers usage.
Gtechniq G1 seems another good option they say it can last 20,000 km and up to 2 years, it is also applied as final glass coating by their authorized installers. I have found many comments of people using it for years but they say it last around one year or less and is not too easy for apply.
Cquartz FlyBy Forte seems to have the best performance on durability and hardness. Corey, from CarPro customer service, told me no coating last an entire 2 year period but they guarantee 1 to 2 year lasting. It is available on their webpage where it also says the coating is not affected by the wipers and it provides resistance to scratches and minor chips. As seen in the video, it has better hidrophobic properties than the WG Uber but of course is the more expensive one and you have to apply 3 layers on windshields but i think this is the winner for what i am looking for.
Another good option is Nanolex Ultra Glass Sealant, it is a german product that can last 30,000 km and up to 18 months, the water start rolling as low as 20 m/h, 5 ml is enough for a full averge windshield. The few comments i have found about it people say is the easiest one to apply (same as PBL Diamond Glass). With the 100 ml you are purchasing it for as low as $0.90 per ml but on their web page says it is out of stock, and that says something.
I have purchased most of the products and equipments i use from autogeek.com but it seems i need to go outside for this.
Happy purchase!
