The summer of 2020 we sealed the terribly faded front cap on our 2015 FF 210UDS with KBS Coatings DiamondFinish Clear Coat. The picture is from September 2020, and when we sold it in the spring of 2023, the front cap and the decals still looked shiny wet. So if you still have good decals or are about to replace them, consider coating them with a protective layer before they start curling and cracking. Be sure to test a small spot to see if they react to the coating. BTW, we live in upstate New York, not the blast furnace Southwest.
