How do I avoid getting white splotches where the dot matrix is?

Elmer's School Glue Gel. It comes blue, but dries clear. When installing your rear window film, first heat shrink as you normally would to form it, the install it as you normally would EXCEPT don't squeegee hard over the dot matrix pattern.

Once the film is in place and the rest of the water is squeegeed out, pull back the film that is over the dot matrix pattern, and put a thin bead of Elmer's School Glue Gel at the bottom of the matrix pattern, then lightly lay the film back down. With your hard card 'push' the glue in an even pattern to the top of the matrix pattern. Be careful when you get to the top of the pattern and the edge of the film, as the glue will make a mess, so have a paper towel handy to catch the access.

Don't push too hard and remove all the glue, you want to leave enough under the film to fill in the air pockets between the dots on the matrix pattern. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
