hi guys,
a previous owner had put a union jack on the white roof of the car, i decided to take them off as they didn't look great and underneath it's left a yellow/off white stain.
i had a quick go over with some polish to see if that helped but it hasn't. it's only very slight but you can see it if you get closer.
any ways to get rid of this staining or residue? or will i have to respray my roof?
cheers
