My dealer has a huge machine that applies some polymer coating every 6 months to your car/4runner. They use it on all of the vehicles Lexus and Toyotas when they arrive at the dealership. They then sell this package of applications to you for a 3 1/2 year period for $500 that is 6 treatments one every 6 months. I alway have done my own but I looked at vehicles that have used their treatments for several years and they look like new so this time I bought the package. It is called AutoMate, it is a specially formulated polymer paint sealant, applied with the fully automatic soft-cloth polish machine. With the package comes a warranty agains't any oxidizing, fading or loss of gloss due to the destructive effects of sun,rain, and snow. Anyone use this or had it done?
