Finish on factory rims blistering/bubbling

[northern_hummer_user]

Has anyone had a problem with the finish on the factory aluminum wheels? When washing my 06 (7000km), I noticed small blisters on all 4 rims + the spare on the back that has never been off the mount.

Would this be covered under warranty? I thought that this might be "regular wear and tear" living in an area that gets salted in the winter.

When browsing in another 4x4 forum, there was a discussion about this same problem with FJ cruiser rims and that some dealers were repainting rims so I thought that Hummer might have the same solution.
