Make replaceable protector patches for your otherwise scratchable LCD screens. I put these pieces of tape on my IPODs and Casio cameras and they work tremendously.
Step 1: Choose the LCD You Are Going to Protect (in This Case an IPOD Nano)
Step 2: Cut a Piece of Clear Tape to Fit. This Brand of Scotch Tape Is Excellent.
Step 3: Place Over the Screen and Stick Down Carefully Making Sure You Get No Air Bubbles.
Step 4: You Are Done! Simply Replace When This One Gets Dirty / Scratched.
