I had the same problem and i just used mothers aluminum polish and you can lay it on thick , if it gets too heavey the neverdull takes it off , neverdull is very usefull but it doesnt work for me as good as Mothers polish for aluminum wheels or like glider said flitz is also very goodCould you type a bit bigger so I can read it from outside? :lolrolling
Try some nevrdull polish or flitz available in any auto store.
Thanks for all the info. The reason I type so big is because I cant see the keys on my computer.
