The rear shock has been sitting on my work bench looking at me all nasty like. So I finally cleaned it up. I sprayed it down with the hose and then hit it with a scrub brush. The dirt and grime were resilient, so I had to soak it with some wheel and brake cleaner and then scrub it again.
It looks a lot better. The chrome bits have some cracking and unfortunately the spring has some rust and missing paint. Looks like I'll need to figure out how to disassemble this thing in order to restore it back to its former glory. That, or find a deal on a new one. Also, when it comes to replicating four "before" and "after" shots like this, its better to be lucky than good.
