I think people just repair them with regular body filler if they're not too badly damaged and cracked.
I used a two part resin/chemical metal type stuff on a Lowlight Ghia wheel that I was repairing, but that was cracked right down to the metal, with big lumps missing. I´d maybe skim it with filler afterwards, as that´s not so hard to sand down.
Your wheel shouldn´t be Turkis should it? It needs to be a darker green.
