First, I only posted this initially in the general pictures thread, but I figured I'd lead off with Slash before Cindersaur:
These were the last gasp of the Black Acrylate. I had to try out Black Professional for Cindersaur, and I rather dislike the texture of the thread-based BP. (And Gray Professional appears to just be Black Professional with the surface fuzzed.)
I tried a whole bunch to match the yellow paint, and never really got close. Fortunately, the bright lighting made it look like a better match.
