@fiveten, thank you, Spiros
@gblair, thanks, George. Had a look at the bike again yesterday and you are right, the chance of getting it repainted nicely is very low. Still these 'home made errors' bother me.
@chinesegeorge, thanks a lot, George. This explenation will help for sure. Luckily there are ten stickers and only eight are needed, so I can experiment first. I do have to admit that I missed the explenation on the instructions.
@kalamazoo, thank you, Allan. I was surprised as well when seeing those stickers, a new experience.
