Love the look of the raw aluminum - it just looks mean. But when I owned my raw aluminum CSX4039 I found it alot of work to keep it looking good. I tried windex, vim, and just about every household cleaner and auto cleaner avaiable to keep it clean looking. What I found worked best for me was to scour it down with a damp cloth using comet (gritty household cleaner). Rinse the car throughly with water then apply a coat of wax. What the wax did was to help prevent oxidation as well as preventing
oil from peoples hands getting on it when they just had to touch. Bottom line is, in my experince the raw aluminum car was as much or more work to maintain that my painted glass car.
