The truss rod cover can be polished to it's original "showroom shine"

again. The hardware on my '87 Spoiler was also very worn, I brought them to a jeweller who polished them and finished them with a clear powdercoating. Shines like new again

I just knew there was a thread about removing sticky nonsense... Quoting Mica:  
 
You can use mineral oil or lemon oil to dissolve lots of adhesives. Like has been suggested, if you can get an edge started, then swab the oil in the exposed area and continue to peel the sticker away.
 
Once you get the whole thing off, you can clean up the sticky residue on the bass with an acetone-soaked wipe. You can use acetone to remove the sticker, but it's hard to controle the placement and evaporates quickly.
 
en welkom, natuurlijk!

Thanks Joram,
 
Wow! A lot of Dutch guys here.

One more here. And where are our Flemish friends when you need them ...

Welcome, Mich.
