I'm not close to doing this yet but I have two questions about 20" rims. In the 60's, Mack used a light gray on the rims from the factory that where used on Dayton style wheel hubs. I have been given some paint info from the museum, but the gray appears to be a little darker than I remember as I believe a few different shades were used over those years. Also, when I get to the point of a repaint of the entire rig, I want to remove the rims and have them painted separate from the hubs, then reinstall them back onto the Dayton hubs. i have been told that on the rear duals, the rims tend to get scratched when tightening the dogs/clamps down onto the hub/rim, mainly because the outside rim is usually initially cocked a bit..... Is this true? I wouldn't want to scratch freshly finished rims....or, have some of the restorers painted them while installed? If so, it doesn't seem like a good way to get a factory fresh look.
