The bottom is done

Well, mostly done anyway, I've sanded it down to 600. The only parts left to sand are those spots under the pads. I started with 150 dry, they used a 220 screen and 320 wet-dry paper. I was going to continue with paper on a pad, but Kelly has this stuff for auto-body work that fits on a random orbital sander. The 400 and 600 grit disks worked pretty well.

Left to do before launch
