Well, mostly done--there are still a few odds and ends left to take care of, like wiring in the solar panel and charge controller and adding some side bracing. But, the majority of the work is done and the car is driveable (after being out of commission while I waited for a day warm enough to paint and then install the lights), just in time for the Green Grand Prix!
I ended up painting it with bedliner. Black+thick covers a multitude of sins; this stuff is UV resistant, abrasion resistant, and impact resistant, so it should hold up well.
I still have to attach the aluminum closeout panels on the bottom; then it will have a smooth underside.
