Peeling chrome is something you will have to learn to live with. Chrome plating aluminum is the problem. The two materials have different expansion rates. The aluminum expands to a greater extent then the chrome, which is also alot harder. The different expansion rate tends to delaminate the bond between the two materials, letting in air and moisture which starts the aluminum corroding. Once it starts you can't stop it. it will worm it's way under the chrome which, at some point, will peel off.
