Cheers lads...

I was after an OEM look, but with less hassles and easier to clean.
So instead of bright silver centres and diamond cut rims, I went with grey centres and silver rims, both powdercoated...and they are still good as the day they were done, 8 years later...despite being sprayed with various wheel cleaners - Wonder Wheels included.
Good as new...but dulled from new...so I tried giving them a quick (2 mins) buff with my Megs G220 machine - and they came up shiny like new!
