Sticker shadow

[GoldOxide_imp]

Purely speculation, but if the stickers were removed after the bike had been exposed to sun and oxygen for several years, the paint underneath may simply be less weathered. Some kind of oxidation-removing polish may be called for; NuFinish that GoldOxide mentioned may do the trick.

(+1) On the possible sun fade of paint around sticker area. If that is the case, I am much less confident that NuFinish will make a difference. However, maybe Forum members can suggest a product that will safely "blend in" the patch area.
