I need some help finding where one can obtain scaled decals (vinyl type) for 1/12 and 1/16 scale hydroplane to my specifications. Or, am I the only one that will have to make them on my inkjet printer! What are my options, or ideas if graphics addresses are not available?

You can try the following:
BelDecal.com - They supply water slide decals

www.cal-grafx.com./index.htm - they do vinyl.

Pacific Graphics makes decals for 1/8th scale boats. Maybe they could scale them down to meet your requirements. The website is www.scalerc.com. Good luck

Thanks hydro junkie. Sent a message to see if they would provide scaled graphics for my fleet of 1/16 and 1/12 scale hydroplanes. Will let you know if they do.
