I believe they're actually clear coated, so take it easy on them. Just give them a giod cleaning. No amount of buffing and polishing is going to make them shine any brighter.After you get them clean, get a sealer or clear wax on them so that the grime doesn't stick to them as bad. I use Opti Seal....it's a wipe on and walk away sealer that is extremely easy to apply, which makes simple work of it
