I would be happy to do others cars (waxing with the P 21 S carnauba) if you are in the proximity of Chicagoland. It's very rewarding to do good work on something. I don't do orbital polishing or the like. Too dangerous and it wears down the paint.
Sometime next spring you should after washing your car, try a Iron remover prior to waxing, etc. It removes the small imbedded particles from pollution, exhaust and brakes from paint and leaves a totally clean surface. You will notice how much better your waxing will come out. Oh, and a Random Orbital polisher is very safe, operated correctly, and with the correct pad brings out added luster. I use several coats of sealant prior to several coats of Carnuba wax, even white cars will glisten.
Very nice Shelby by the way, I just purchased a red with white stripe '66 myself, looking forward to enjoying it this fall.
