If anyone needs to make instrument decals, here are the ones from when I did this a couple of years ago. You won't need the speedometer face plate on this sheet, since it was used to convert the Speedhut electronic speedometer, and there are two beige dots which were used to mimic the original 2 tone dots (a slightly different style I used). But feel free to copy these and use, modify, whatever. I think I also have some SVG files from the work I did, but don't know if you'd need them. Hint: if you take these to FedEx/Kinko's, they have excellent color laser printers and are happy to print on white waterslide paper. When I did this (maybe 4 or 5 years ago) the cost was $2 per page or less. And you may remember the frankenspeedo creation...I haven't decided what to do with it yet.

Originally waterslide decals were made with a heavy gelatin compound. This stuff was terrific, but the process required some very special equipment and special gelatin. You could not have printed them on either an inkjet nor a laser printer. Today's printable waterslide decal paper is a forward step in that "everyman" can use it and since it comes in either white or clear you have a myriad of possibilities for it. As for how it lasts...very well. Once it is applied and cured about the only way to remove it is to soak in vinegar and it may take a while. But as I've mentioned here many times, if you use an inkjet printer the decal must be sprayed with a clear paint (enamel, urethane, etc). If you use the laser print paper, get your decal to the proper size and take this file (jpg file) to FedEx/Kinko's or any commercial printer with a color laser printer (unless you're making black/white only and then you can do that on a common laser like HP, Brother, etc).
