Hi, sorry that your housings are looking so bad. I was thinking, that if mine get worse, that I would take them off and have a chrome shop buff them out and spray clear coat on them myself. I believe that there are only four screws, two on each side and some sealer around the top and sides holding them on. Also an anodizing shop can buff them out and maybe apply a clear anodized coating on them. Mine have it too, but it doesn't show very well in the pictures. The picture on the left shows the plastic bezels looking bad and the picture on the right shows the plainer stainless steel bezels.
