AlBriCo 805-482-9792 AL Schioppi PO box 3179 Camarillo, CA 93011. Hope they are still in business. They did mine several years ago at a reasonable price. They polish the brass to a mirror finish, coat with a liquid aluminum, seal it with glass. No more tarnish and the lights are bright, no problem with night driving. Let me know how you make out. timandjuliawolfe1@roadrunner.com
