Car weighs 2,000 lbs as it is carbon fiber with all aluminum 496 FE. As far how I did the wheels. John I used your approach with paint as I really liked the wheels on your Kirkham but wasn't sure how that would work, so a friend of mine had a bent Cobra wheel and I started experimenting on it with primer and paint. Sanded the wheels with 220 and then I started with a light green etching primer, added some gray primer and then flat black paint. The key to the look is with the green still tacky then dusting the gray and flat black and start rubbing with black mechanic's gloves on to get the vintage look. Even the spokes looked really old. Sometime the paint would smudge or get rough which made it look even better. I took me about 3-4 hours per wheel but was worth it as I really wanted an old magnesium look and they came out just as I wanted.
