I applied the product to the VX and waited a week before washing it, I went to the car wash and washed it as I normally do (run of the mill do it yourself high pressure car wash) after I rinsed it I noticed some area looked discolored so I drove home and waited to see how it looked after drying it. Well it looked like crap, some of the product washed off and it was then splotchy grey and black. They claim it dies the plastic but it did not on the VX. I cleaned and prep'd it better than they instructed so I do not believe that was why it did not color the cladding. I plan to remove it all at some point and just live with it the way it is, I am not impressed with the results.
