Think I can probably guess the answer but just to be sure.
My recently purchased +4 is fitted with chrome wheels which are just showing signs of rust.
I'm not a great fan of chrome wheels anyway plus the original car had red wires fitted.
So....can you get chromed wheels prepped and sprayed/powder coated? Or is it a case of changing a set? Or is the botheration and cost of doing the former mean it's easier to do the latter?
