Is this a coincidence, or what?
Not three hours ago, my GF comes out of the TV room with the Bourne Identity DVD that she rented from a local shop; she told me it wouldn't play and was worried she might be liable for the damaged disk's replacement.
No wonder it wouldn't play...there was a spot on the disk that looked like someone had dropped it on a gravel driveway and then stepped on it a couple of times. I checked the label side for scratches, since that's the most delicate part of the disk; luckily no light shone through anywhere.
I grabbed the Flitz and a dry paper towel and went to work.
See, Flitz has finer abrasives in it than toothpaste has, and can be used for polishing fiberglass, plexiglass...and polycarbonate!
I used my finger and a small dab of Flitz, and proceeded to polish the damaged 1/4 of the disk, beyond the scratched area to keep that spot from wearing too much, back and forth from edge to center (being sloppy about it), and I continued polishing until I could feel no more roughness. It took less than 5 minutes.
I rinsed the DVD off in the sink, and wiped it dry.
Not only was the disk pristine in appearance, but it played perfectly as well.
That is how I take care of damaged optical media, and it works. I'll use Crest in a pinch if I'm out on a call or at a friend's place, though!
Good luck, and check the label side first! If you can see light, you'll need some Chrome paint from the hobbyshop.
PS. This was a rather sucky movie, from a firearms viewpoint at least....the director apparently believes that a silencer somehow quiets a supersonic bullet to >phut< levels just by resting against the outside of the barrel! Seriously, in at least two scenes, a 'sniper' removes the can from the rifle only to reveal - you guessed it - a FULL-LENGTH, SOLID BARREL.
Gotta love HollyWeird.
