I’m about to start painting my Rally IIs. I’ve ordered the paint kit for Ames. When I got them sandblasted they sprayed on a grey primer. For the back side of the wheels I’m spraying a grey Valspar anti rust armor over the primer. It’s exactly the same color as the primer. Do I also spray the inside of the wheels too (between the beads)? You know, where the air gets installed😉.
