After using many products, I found the best way to protect your chrome or forged aluminum wheels, and to keep them sparkling new, is to use Meguires Ultimate Quik Wax. Just spray it on an wipe off with a soft cotton or microfiber towel. Super easy and does a great job-takes only about 2 minutes per wheel. MeguiarsDirect.com:Ultimate Quik Wax Ultimate Quik Wax
