It was suggested that I spray the painted lamp clusters with a clear high gloss enamel to protect them. I also sealed the lamp lenses where they had cracked with an epoxy. I cleaned up the rubber with mineral spirits and then treated them with “Black Again” which made them look and feel good as new. I’ll replace the cage nuts with stainless steel ones and I’ve done that with the screws as well. Lets see how they hold up.
