Windshield rain coatings??

[Redd]

The Project Farm test does not include longevity test especially if you use the wipers. My experience with Rain-X is that it does not last. Glaco Ultra lasts much longer for me.

There's two kinds of Glaco windshield coating - normal (orange) and Ultra (black). Get Glaco Ultra.

Thanks, I just ordered some to try.

I would recommend Armour Detail Supply glass coating, Infinity Wax Diamond Vision glass sealant (insane sheeting but low durability), Jade Amethyst Glass Coating, or the new C6 glass coating. I have only tried the first two of this list, but I am confident that these 4 are some of the top formulations out there.

If you want durability and don't mind a coating with higher sliding angle, then the DPT Diamond Glass is very easy to use and SUPER durable. It's still working on my Mazda after 18 months with wiper usage although it has weakened some. The catch is that the droplets don't run off until 40+ mph speeds.
