I am going to by Autoglym alloy cleaner as well as the sealant, but there is 2 to chose from depending on the type of ally wheel finish. I have a New Fiesta titanium with the standard wheels that come with it. Does anyone know what the finish would be. Example being chrome, lacquered, polished aluminium, anodised, chromium, painted and plastic trimmed wheels. Or is there any other cleaners and sealents that are better?
