My new Yukon says that the wheels are chrome, as opposed to other gmc cars that do list as chrome-clad. How can I know for sure that they are actually chrome? I plan on having them taken off and coated but that probably won't be until spring. Until then I would like to decontaminate and seal with something easy. I see that Iron x says not to use on chrome, what are my options here? If I'm looking to carry me a few months would Hydro2 be a good option for a quick and easy fix?
