:welcomebanner:to the forum! I'm not sure what Adam's products you already have, but if your wheels feel gritty I'd start with the Deep Wheel Cleaner. Beyond that, I'd correct them as you would your paint: clay, polish, seal/wax. On the polish, start with the least aggressive method necessary. So hit a sample area with Fine Machine Polish, and if that's not doing it go to Swirl & Haze Remover or Severe Swirl Remover as necessary. When you get them corrected, apply Quick Sealant for protection and to make them easier to clean in the future. If you want to add some shine, apply a coat of Brilliant Glaze and Americana.
Also, try to post some pics of the wheels to get the best recommendations.
