That was a much bigger pain than I was expecting. A quarter of the way through I was ready to quit.

Back when I worked in a jet ski shop, I used to apply decals on boats back from the body shop. I sprayed soapy water on both the hull and the decal, set it in place and squeegeed the water out from under it.

I decided to try it with this and it turned out good- much better than when I trying to do it as I saw on videos.
