Matty, no special tools required, a lot of sandpaper is all really and time and patience. Lots of time and patience. I will probably be doing mine over the next year depending on time and space. Took me about 4 days last time I did wheels, although only that quick because it was the middle of the hotspell in summer so drying times were quick.
Pete, thanks for the offer, haven't decided on colour of wheels yet so not sure on what colour nuts I want. And I no rush, may get back to you once decided though.
