So, when I got my WOLF last year, several of the stickers were in the wrong places and were in poor condition...
... as you can see from the arrows.
I bought replacements from cobrastickres.com and stripped the old ones off, but the WOLF was left with loads of horrible gooey gunk on it. My uncle gave me some stuff called 'Sticky Stuff Remover' which worked a treat.
Nice and clean(ish) and bereft of stickers.
Nicely restickered. Did have one minor disaster where i dropped one sticker as I was trying to put it on and the bloody thing went and fell into my keyboard between the keys and I couldn't get it back out. The sticker sheet also included extra stickers to go on the red missiles but I've not put them on yet. I'm in two minds whether to, since they're not originals. They also included numbers to give the WOLF a 'fleet' number if anyone was of a mind to build a pack of WOLFs. I've not done that, since I only intend to have one.
