I have 1 single coat of collinite 476s on my GTI. I put that on in september. As of right now, with never washing the car since then and going through all of the winter so far the paint still beads as if I waxed it yesterday. I just went out to a coin op car wash place to just use the high pressure and spot free rinse and the water beaded up and rolled off so nice. Now all I need to do is wash with Optimum No Rinse tomorrow to get all the hazy dirt left over from not actually washing my car just rinsing it off. One major thing to consider before trying out Collinite 476 is that you need to put a very very thin coat on your paint or it will take you hours to buff off like what happened to me. Other than that, wax comparison tests have proven that 476s is one of the most durable waxes you can buy and it's only like 15.99. I'm about to test out some Poorboysworld Natty's Blue paste wax which is also a very durable wax but a lot easier to use.
