Wow, glad to see that my case wasn't just an isolated one. It seems to me that the clear coat they put on is extremely thin, since when sanding with 1000-grit, the white milky water you get (paint) quickly turns dark grey (down to metal) in a matter of a few strokes of the sand paper.
And yes, mine are from American Muscle. A friend of mine got the black DD Bullitts as well and last summer the clear coat was peeling off the dish lip, he might also have to go through this in the spring time.
Luckily its not that hard to do. One thing I didn't do, but I'd recommend is using 800-grit on the tire lip, since that area requires a helluvalot more elbow grease to shine-up. Better yet, if you have a dremel, use that.
I applied the clear-coat only on the lip, however I did get some over-spray on the base of the spokes, but you can't really tell. Depending on how finicky you are on the little details, you might want to mask-off the spokes when you re-clear the lip. Don't worry about the tire, the overspray will just wipe-off (you can see in one of the pics, it looks like alot, but it wiped-off easily with a rag).
Good luck with it, man, it should take the better part of a day to do a good job on it.
