The problem is once the lacquer's removed, you'll have to keep on top of your polishing. It may however be possible to purchase clear vinyl, and cover the fresh aluminium, protecting it from the elements. (Audi use it on lower areas of the rear wheel arches on certain models vulnerable to stone / grit chipping).

Varnish it, International Yacht Varnish or similar
