Hi Wayne, I have to agree with Gary on the construction of wheels. The OEM CAV wheel is cast and machined from one piece aluminum. These wheels are extremely high quality, of the past eight wheels we've had balanced, a dial indicator has not shown more than .001" runout. As for porisity, it's possible but unlikely.
I hear .005 >.011" runout on some welded multi-piece wheels. That can make balancing the wheel/tire assembly quite challenging. However that going off topic...
About the paintwork, the factory finish is absolutely top shelf as anyone who's seen a CAV can atest, but the "Almighty" works in strange and mysterious ways, and not in the CAV paint shop! I can send you the paint codes for the original PPG tints if your looking at a respray or touch-up.
