Hi Ed,
I have never had it done so I can't speak from personal experiance. There is a place called Wheel Techniques off of Dela Cruz (near the airport) in San Jose that can do anything to a wheel. They have straighten some rims for me and did a good job.
I don't know of any place in the Monterey area. You could send IllSMOQ a PM and get his recommendations. I sure here can point you in the right direction.
