Dear Sticky
I have a pair of sl600's, oritinal owner, same problem. I am considering veneering at this point. There is nothing I found that worked, and I started with mild soapy water, then a few over the counter things. Aluminum is a tricky substance to paint, and my guess is that over time, the nextel like finish started to have a reaction to the alum.
good luck.
