Here's the deal.....
I'm getting this strange 2-toned finish on aluminum.
It starts to appear somewhere between 320 to 600, during both wet sanding or steel wool,
before I move to the buffing wheels.
see picture
It stays like that all the way through the three buffing wheels.
What is this?
What's causing it?
What can I do to correct it, and/or stop it from occurring?
Thanks!
Mike
