I've heard of people using toothpaste to fix scratched discs. Hell, if it works.........cheap way out.
I bought a disc repair kit several years ago when movies I rented kept "stuttering" on me.
This is close to what I bought.
Same company, but a little different style. Been a few years ago and I didn't even know about the toothpaste trick back then.
I've actually saved several game discs with it, but I would be willing to bet that the toothpaste process would work just as well and cost less money over the long run.
The guy in that youtube video is using WAY to much toothpaste though.
I would start with about 1/5 of the amount he used (if that much).
I don't have any badly scratched discs at the moment, but I have been thinking about trying to use car products for deeper scratches on discs. Take a dab of cutting compound (for the really deep chit) followed by a rubbing compound, followed by a polishing compound.
I do have some discs with some relatively "fine" scratches that have been bothering me (don't know why........they play just fine) that I have been thinking about trying the polishing compound on.
I may even have 1 or 2 (with a few little deeper scratches) that I may try the rubbing compound and polishing compound.
Think the wife would be amused if she walked into the room and I was using an r/o buffer to get a really nice shine on the discs? I highly doubt they would survive being hit with a high speed buffer (and could cause serious bodily injury if it was launched across the room by one).
BRING ON THE TURTLE WAX!!!!!!!!
Seriously though, I may try and find a couple test discs and see what the combination from cutting compound to rubbing compound to polishing compound will do. Hell, I may even take one and shine it up with some Carnuba wax (just to see what the outcome would be ).
I do think that (if you already use car products) it would be cheapest to use the compounds instead of toothpaste (even though toothpaste is quite cheap and readily available). If the scratches are really deep, you could try a combination of rubbing compound and toothpaste......... or just a s-load of "elbow grease" and toothpaste.
Good luck on getting the disc going.
I would much rather go to my grave not needing my gun, than go there wishing I had it.
