Introducing Meguiar's Next Generation of Technology. Engineered Synthetic Polymers (ESP) Our expertise in Engineered Synthetic Polymers (ESP) has created a completely synthetic car wash concentrate that loosens and emulsifies even the toughest dirt and road grime while synthetic lubricating oils glide them off the surface without marring the finish. This cutting edge formula is gentle on all painted finishes as well as rubber, vinyl and plastic components. Meguiar's NXT Generation Car Wash leaves an eye-dazzling finish by itself or prepares your finish for application of Meguiar's NXT Tech Wax. Engineered water softener helps reduce deposits in hard water, leaving behind a spot-free finish.
