Here's my writeup on color sanding - some day I'll add pix.

I'm still doing little body work stuff here and there - I haven't sucked up the courage yet to pull the top and windshield and get serious. I have a track day on the 26th and another on the 7th and I'm hesitant to get it disassembled too far for fear of not having it
assembled in time. I guess if it came down to it I could throw the top back on for the day, then take it out again when I got back.
