These are incredibly easy to install, just follow these steps:

  1. Clean the area with the supplied alcohol wipes. Pay attention to the corners and wherever dust might accumulate
  2. Peel the Armor section from the backing sheet
  3. Carefully place it, using the back edge for alignment, then allow it to lay down
  4. If it's correctly aligned, grab a cloth or clean shop rag and apple pressure to finalize the install. If not, simply peel it back and try again until satisfied with the positioning.
