The self adhesive decals like Jim sells can also be tricky. If I understand correctly, you can also use water to help position them and then use a squeegee to flatten them down.
It's actually a solution of 50/50 water and baby shampoo (or some soap). The window tint guys use a soap solution too or maybe something
professional grade. I think baby shampoo was the natural choice for tint, because it rinses clean, doesn't haze or leave residue. Something like that...
