The other day while watching History channel's "Modern Marvels" they did a segment on "GlassCoat" by Simoniz, seemed to good to be true. They offer 7 year guaranteed protection! The products does not seem to be ready for release to the public, but is being offered at new car dealerships, as an expensive option. Glasscoat is some sort of sealant, I guess the final products NxTech etc. are sealants as well, so it comes down to how long a sealant lasts? What's Mequiars take on this type of product? Is this the future, for car care products. I have a garage full of Meg. products & believe in: 2 bucket wash > clay > polish > wax method Every 6 months. My Audi's are gorgeous, using the Meg. way, I guess I'm just getting old, it's allot of work.
