I haven't tried making tank decals yet, but did use the testors white decal film to make some for another project and it worked very well. One advantage I see, and will probably use this for if I can find the proper font, is that you can number tanks to be in the same platoon by changing one digit in the number on German tanks. The Peddinghaus decals are nice, but I'd like my Tigers to be in the same unit and they don't sell spare numbers to change them around if you want to.
