I started custom painting police cars in 1/24 & 1/18. My first project was the toughest. The old green and black nypd. With few pictures to go by,I was forced into making my own decals. What I thought was once a pro only's task became possibe with a little research. No expensive programs to buy, and you don't even need a printer, since Kinko's will print the decals for you for penny's. All you need is a quailty straight photo of the car's graphics crop re size and you have your own decals. Check out badge764's videos on youtube. The guy is an ex-cop super nice guy, and will walk u through. Good Luck
