A "SPOT" of bother..

[samass]

Rub down and respray is pretty much the only option id have thought... Not a full refurb mind, just enough to key it

guessing you mean spraying with the "new" colour

unless you have any of the old stuff left, but seeing as you bought the new stuff to touch up the old stuff, im guessing not.
you might be able to get away with just doing the one wheel, if not, at the very least just two on the one side
