I was skeptical of the claims by Turtle Wax, and some of the reviews on YouTube. I am very happy to say I was proven wrong.
I applied this wax, following all the directions, and the results are better than I have ever seen in any wax. The build up of road salt and dirt was easily 75 percent less than normal. And the crud that did build up would literally slide off the car with just a heavy frost melt! The 3 vehicles I waxed looked like they had been recently washed almost all winter (without being washed once in 4 months). In pre freezing temperatures, high humidity would actually bead on the cars.
4 months later and today's rain beaded up beautifully.
5 stars plus for quality, value, and ease of application. Follow the directions and you won't be disappointed.
