After finding the right spot on your window, take
your etching and peel apart the two layers. You'll notice that
one side is sticky and other is not.
Take the sticky layer and place it face
down onto your window. Try not to cause any bubbling when
doing this, it'll wrinkle the sheet.
Take the plastic applicator and scrape
it across the surface of the sheet. You can use your hands
too, but the applicator is a lot straighter and can push most of the
air pockets out.
After that is done, peel away the top
layer of the sheet. Make sure you do not peel away the
etching. That should not happen if you pressed down hard
enough using the plastic applicator.
