I really like the look of it, and recently got a quickfire rapid of my own. Mind describing the process that went into sanding everything down?
Sure! First you have to take the cover off. There's only one screw at the bottom, underneath the white warranty sticker. Then I used an old gift/credit card to slide under the front and rear edges to separate the cover from the base.
I think the paint job is done in three phases. Base coat (either black or gray), then logos, then clear rubberized coating on top.
I started with a pad of Scotch-Brite. I found it worked a little better than sandpaper to rub off the rubberized coating. You might want to do this outside cause rubber flakes will be floating everywhere.
Then I went with (I think) a 600-grit wet/dry sandpaper to take off the logos and base coat. I just dipped the entire cover in tub of water to keep it constantly wet.
After getting all the paint off, I started standing the plastic in one direction for all the surfaces I wanted to look brushed. I eventually moved on to finer sandpaper until the scratches looked the way I wanted.
