Sounds like a painful process, Trevor. Hope you get your range of motion back soon. I am now 6 weeks from the surgery, and hope to be allowed to start PT next week.
I have plodded along with the build as well as possible with one hand. The body has been sanded to 220, then two applications of Timbermate with sanding. I've been spraying with a black base coat and sanding back runs for about 3 days. When that is finished, I plan a light wet sanding at 600 to smooth the surface some, then try the fancy Colorshift paint. Kind of just feeling my way along. We'll see.
