This step produces a lot of small plastic particles and it's recommended that you wear safety glasses to keep them out of your eyes.
Turn the shell upside down so you can remove the protective plastic backing. If you don't have any blue lettering on the inside of your shell, then we already removed it for you.
Start peeling the backing using a utility knife. The folded corners are a good place to start.
Use your hands to peel back the rest of the sheet.
You can clean up melted areas of plastic by gently scratching at them with the utility knife -- the polypropylene doesn't scratch too easily if you're gentle.
If any of the small holes in the shell still have plastic in them leftover from the laser cutting process, carefully poke them out with a screwdriver or utility knife.
