I read an artical in model aviation mag by Bob Aberle. He gets special water slide decal paper from Bell Inc . Their web site is
www.belldecal.com, it works great. You use any word proceser or I use adobe art prgs to make anything you want , from nose art to to tail numbers and so on. Then you print them out on your printer. Then spray them with Krylon clear or Krylon matte that you can get at arts and craft stores like ac moore. This seals the ink on the decal from fuel and water and other solvents. Cut your decal out put it into clean water for 45-60 seconds. when the decal starts to slip on the backing just side it off on to your plane.wipe off the excess water and press out any air bubbles. let it sit for about 3 hours. they are really nice . I did my name on the side off my edge 540 t with cursive hand wrting from word perfect. you can make it any size you like and they weigh nothing. Go to the web site and check it out they have all the instructions. I bought the 8.5x11 starter set with 10 clear sheets and 10 white back sheets for 17.00. you can make a whole bunch of decasl whith it. they work just like the ones you get with plastic models.Hope you try it they are great. your only limited by your imaginantion to what you can make.
