Jules, I gave mine a light sanding to smooth down and remove the deteriorated stuff in the translucent part. Then put another coat of resin on them. On the worst ones, I also put a layer of fiberglass on the underside too. After curing, I sprayed clear acrylic, obtained from an auto discount store, over the resined part. This looked great, like new. This treatment lasts for about a year, and is beginning to discolor now, although the resin and glass are fine. Next time, I will try using the Awlgrip clear acrylic paint as that should hold up much longer than the auto spray paint. Matthew
