Hi Phil, yes, I used rattle cans, Hycote Wheel Silver was the colour, came out much darker than I expected, but it's grown on me. I took a lot of time prepping the wheels, loads of time rubbing down and filling the kerbing and scuffs. There are still a few areas where you can see minor imperfections, but you have to look very closely to see them. I used a proper alloy wheel filler, and deflated the tyres so I could do the edge of the rim. I used playing cards tucked inside the bead to mask the tyres off.
It was a lot of work and I sometimes wish I'd paid £300 to have them done properly, but when I kerbed one a month later, at least I could repair it myself!
