So a bunch of the guys at work pooled together to buy a sand-blasting cabinet. I ran out of work to do by about lunch time so I spent all afternoon and most of the evening using a grinders with brush wheels to strip the frame down to bare metal as much as I could, then used the sand-blaster to do touch ups in the difficult-to-reach spots. I then applied two coats of flat black Rustoleum.
The battery rack is also painted. I'll have more photos to share once the bike is back in one piece.
I apologize for not having any in-progress photos. But the work was really messy and labor intensive. I was afraid that if I stopped to take breathers and take some pictures I wouldn't have reached the point I wanted to be at by this evening.
