If your gonna do anything, try annodizing or powdercoating. Your can's would probably be about $40 total for powder coating, and same price for annodizing.
For powdercoating, try Airborne coatings down on 39th and Tulsa.
For Anno, go talk to Kenny at Precision Annodizing which is on the other side of I-35 from Blazers Ice Center. Good luck, glad you got the rings worked out.
