I had mine refurbed and maintained them fastidiously afterwards. Cleaned weekly, sealed etc. They lasted about 12 months before the first sign of whiteworm returning. Now another 12 months on and there are quite a few patches and also the lacquer is cracking and pealing on the inside of the painted wheel cutouts. Currently deciding, do I have them polished again and last another two years, have them painted or get rid and replace with a wheel that doesn't suffer this issue...
