Bought a kit at walmart, wipe new, haven't used it yet but was wondering who has used what and how have the results been. This exterior body cladding on one of my vehicles is getting gray and faded with age. I have used Meguiars and some other products in the past but they don't last very long and are actually just an applique. The wipe new has mixed reviews online but actually appears to change the top layer of plastic through some chemical reaction. Any thoughts?
