I'll have to chime in on this. I work in a Cement plant. Any one familiar with the type of industrial fall out of a cement plant knows how difficult it is to keep a vehicle clean. I was turned on to Tec 582 about 6 months ago. I have used everything you can imagine over the 15 years I have worked there. This in combination with Turtle Wax Graphene is by far the best combo I have used. I've used Chemical Guys Jet Seal, DuarGloss all kinds, both types of Collinite Insulator Wax which is excellent as well. I used to have to use vinegar in a pump sprayer on a regular basis to help assist in getting the lime and clinker dust off the paint of my truck, now it just blows off with the pressure washer. I foam cannon and blast off, foam cannon and hand wash. I uses Tec 582 every single time full strength when I dry the truck. I probably spend too much money washing vehicles, but I work in an absolutely horrible place for vehicles. I have never had anything impress me like this product. I do what to try the stuff with Graphene next time see if it's any better.
