All the wheels are painted using Halfords rattle cans, I got brilliant results with them , as long as you spend plenty of time prepping them.
No picture of them on a car as I do them to sell on. A bit of a hobby.
If they are Halfords cans I reckon that is their Steel Wheels colour, some of mine are painted in that and I like it. Currently got a mix but did have satin black most of this year which went well with the red car and black roof I have. Over the winter I plan to get them all black again.
