probesport is correct
EASYOFF is the way to go
cheap and effective
on removing all anodizing
because i have done a few wagoneer grille surrounds and wagoneer alum bumpers, i sprayed on, waited 15 to 20 min
used a steel wool soap pad and water to wash it off and then
went from course to 2,000 grit
then polished with mothers billet alum polish
shines great, i just put a coat of light polish on it to preserve shine.
in my opinion you run a great risk of clears giving trouble down the road.
i think that if you even "half way" keep your vehicle looked after it will not need anything other than routine cleaning an maintenance to keep it shining.
