That product doesn't make any sense whatsoever. Under the vinyl, the surface has been completely protected by the vinyl and the rest of the areas have oxidized. So, according to this ad, this stuff you wipe on and it must instantly
only oxidize the protected areas and dull them to the rest of the surfaces.
Sounds more like an ad for adhesive remover where after taking the vinyl graphics off, someone didn't remove the excess glue which will collect and attract dirt and they are referring to that as ghosting.
Be careful as to how that stuff is used.
