[title] Polypropylene Shell
[* black] Turn the shell upside down so you can remove the protective plastic backing.
[* black] Start peeling the backing using a utility knife. The folded corners are a good place to start.
[* black] Use your hands to peel back the rest of the sheet.
[* icon_note] 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.
[* icon_caution] 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.
[* black] If any holes in the shell still have plastic in them, carefully poke them out (away from your body!) with a screwdriver or utility knife.
