Re: Griot's Glass Sealant
I've been using the Griot's Sealant for about a month now. My yardstick for performance is the speed threshold at which water flies off the glass, eliminating the need for wipers. A fresh coat of GG lasts about 2-3 weeks for me, at which time it needs about 40 mph to shed water well. Definitely a step above Rain-X, which I've used since the 70's, but miles behind the durability of Aquapel. I'll use it through the fall, but I'll be going back to Aquapel again before winter. Aquapel's quite pricey, but I can go the entire winter between apps. Regardless of the sealant, I've found that using Stoner's Glass cleaner with "rain repel" seems to extend the life of the product.
