Have a wheel repair company in SA take a look at them. I had some work done on my OEM wheels and you would never know they were repaired. If you choose to go this route, they may also have powder coating services to take care of the color change, too.
Here are two companies I found in the SA area -
Alloy Wheel Repair Specialists of Texas: Servicing San Antonio, including Bastrop and Caldwell
Wheels America Wheel Repair San Antonio
Good luck and post some pics of your wheels to get feedback from the forum.
