I had an aviation grade sealer applied from the dealership. It is from Cilajet. It comes with a 10 year warranty. It was applied to the paint,wheels,glass and interior. Nothing sticks to it. No bugs, tree sap, brake dust, bird crap.....nothing. You only need to wash it. No waxing or anything. If you get a stain on the seats that won't come out, Cilajet will pay to recover the seats.
