I purchased my 2008 AV 10/8/18 and bought the paint, interior, headlight lens, alloy wheel, black trim/molding protective treatment that they applied at the time of purchase. It has a 7 year warranty, so they will pay to reapply any time there is damage and they will also clean anything that ruins the protected surfaces. Can I really expect this to last for 7 years without reapplying? Anyone have any experience with this?
