I have quick qustion?
When you start polishing your frame you start with 220 sandpaper to get the anodizing off. How do you tell if the anodizing layer has been removed?
I've been sanding and sanding and I can' tell.
You will be able to tell. It will be a completely different color and feel. If you aren't using an orbital or a mouse sander fot the 220 grit, I would suggest it. It takes about a quarter of the time with a sander than by hand.
