I found using the wet method on glass takes a little longer to set up, but it does work. Here are some decals he made for me to go on my rear window. Which I know your going to love.I gave Pixel Hut a shot for my rear window (subdued US Flag) and it was a total fail (wet method). Decal would not stick. Complete waste of $45.00. Could have been my fault, but I don't think so. I followed their directions to the letter.
