Re: What the heck?
Well, I started back at 320, used the same sanding routine but then loose/emery and loose/white. Used twice the compound and half the pressure and more time. There was no heat buildup, but I got the same result. The more glazed the surface became, the more the haze showed up.
So, it's either a flaw in my sanding, or pores/grain in the metal. I might try stopping at emery if I can get the wheel marks out, but it doesn't look good.
Times like this I feel like selling my equipment...
