John, have you heard of and/or used a product called Mother's? My friend recommends it for polished parts. He says that you put some on a final polished part and bake it in the oven for a while, and it prevents the aluminum from discoloring afterwards. Sound likely/familiar?

I just spent the morning looking at hundreds of chips and parts over at the powder coaters. Wow - theres at lot of choices - I'm probably more uncertain of the frame color now - than before I went. :-D

Some powdercoat colors are a two-stage process, with one color baked on first, and then a second overlying it. I wonder if these particular colors are as stable? I think it may be the case that the second coat adheres to the first coat poorer than the first coat adheres to the bare metal. If you're thinking about such a color, you might want to ask them about it first.
