What it does
- Protects the paint from UV fading, bird droppings, bug splatter, road salt, tree sap and light chemical staining
- Makes washing easier: it's strongly hydrophobic, so water beads and rolls off, and dirt doesn't stick as well
- Adds gloss and depth: the finish looks richer and shinier
- Lasts: typically 2 to 5+ years depending on the product, how the car is used and how it's maintained
