Nexgen delivers on its promises of a mirror finish. My 2017 Ford Super Duty literally looks like it has a brand new paint job because it shines so brilliantly. That's not hyperbole. The Nexgen finish is so slick, the spray dispenser literally slides off even slightly curved body parts like the hood. Bugs and dirt come off a treated surface pretty easily. The longevity isn't as robust as I'd like, but it may be a result of how lightly I apply the product. See below. My only complaint is the dainty spray dispenser the product comes in. It produces a very fine mist that seemingly floats out of the nozzle in a cloud more or less in the desired direction. I find it has to be used carefully in even a slight air current inside my garage with the door open and a light wind outside, i.e., 5 - 10 mph. The product is too expensive to spray onto a cloth in sufficient quantity to apply.
