I posted this in the other thread. Seems like it would do good in this one as well.
Anyone else think of trying "Birchwood Casey Aluma Black Touch Up"? Costs about $10 for a bottle.
It is used to touch up Anodized Surfaces on guns. It actually chemically reacts (selenious acid) with the exposed aluminum scratch and makes it black again. From gun reviewers it seems to work pretty well. And doesn't affect the rest of the anodized finish. I wonder how well it will work for our black anodized iphone's.
Again this is different than a Sharpie or even the Birchwood touch up pens (which is paint) that come in matte and gloss black as well. This actually changes the surface of the metal.
My only concern is how it would react to the plastic antenna points if those areas near it were scratched. It comes in a plastic container so maybe it will be fine? I would also probably use painters tape to mask other "vulnerable" areas. If replacement backs weren't so much money I would experiment on it.
Thoughts...?

I have used this product on aluminum gun frames numerous times with very good results. Main points are to degrease the surface thouroughly before application. Also I would be very nervous about getting this stuff on any internal electronics, since I believe it is acidic. That said, take reasonable precautions and you should be good to go.
I would post a picture, but there is really nothing to see.
