carnuba "paste" wax is a very good product with some longevity. It's available at any Auto Parts store. Some others will recommend Zymol, but the product beads/protects for only a short period of time. Just make sure you do "not" touch the black trim with any wax, it will turn white, and it's very difficult to remove. A polish is only needed typically once a year, for light scratches and light oxidation. Hope this helps and congratulations!
