Here's another news flash for you....That purple stuff will turn aluminum very dark, almost black and you can't polish it out (I don't think so anyway). It seems to actually convert the color..
It's great stuff and I always keep some on hand.... but you have to test it on anything you haven't tried it on before. I think the big issue is that it contains Lye and aluminum does not like lye.
