It's an anti friction coating that is supposed to provide me with 0.01% increase in throttle response.

Actually, the guy who welded them runs the spray booth in our big machine shop so I rekin he's kinda anal about making sure everything is well painted before he delivers. I was thinking about shooting them Proton with a rattle can before install but haven't decided. I've never been concerned with how the under side of my vehicles look but thought that if I wanted it nice looking later ... now was the time.
