Darkhorse - that ship looks really good! I know it's been fighting you, but I think you came out on top! Sorry for not replying sooner about the decal printing companies, but I have a slight problem recommending a company in the USA to do it for you. DRAW! decals used to take orders like that, I don't know if he still does. In Germany I have ordered from a company called Decalprint - they did a fine job printing decals for my truck, including very nice silver patterns. And in Poland I order from a company called MeliusManu - those boys know their job well, but sometimes take weeks to print something for you.

Melius Manu also printed very nice white and silver pattern for me and their decals respond very well to Micro Sol&Set, and Solvaset, too.
Thanks for sharing and good luck with that guitar
