Have you checked out  www.dewcollector.com or 
wwwmountaindewbottle.com they may be of some help.
What I have done is I got in touch with a graphic art
 designer and he has made a decal for my  7Up slider
and he made a stencil for my Cavalier  C-51  . 
And both of those turned out great, I hope this
help's.
