I've heard that you can use micromesh to repair DVD's. Anybody ever done that successfully? How did you do it? What grit (color) did you start with? Did you use them wet? I've got a DVD that my wife wants me to fix and I don't want to screw it up. Thanks.

try it on a different one first.
I've never tried it, but i am familiar with the idea behind it.
The surface of the DVD is just a thin protective plastic layer. The actual "data storage area" is beneath that, but scratches on the surface diffuse or reflect the "laser" so the device can't read it properly.
You dont want to start too coarse. If you remove too much material you'll actually damage the data. Your goal should be just to remove the scratches from the protective covering. If you sand through it (or the original scratches do) the dvd is beyond repair.
 
I thgnk this might be a good case to work backwards .... I would start with PlastX or Plastic Polish 1st (on a sample disc you don't care about) If that doesn't do it then try Novus 2 and finally your highest grade of MM. Just my opinion ... I haven't tried it!

This one of the easiest and most effective way for small scratches. Just rince with water and whipe dry. Baking soda toothpaste works the best.

Brasso can be used too.

If it does not solve, lenny aproach is the best. Professionnal services uses buffing compound and a flat buffing weel. In dramatic cases, they uses 2000 or 3000 grit paper, then the compound.

You have room to play but not too much so don't start with a too agressive media.

Be carefull not to scratch to top of thr DVD as this is where the reflextive part for the laser is and the data will be unreadeble is this part is dammage.
 
Yeah, I've used Turtle Wax, toothpaste, a resurfacer (fine-grit micromesh on a wheel) and other stuff to fix discs. Try starting at the middle of the spectrum. Go STRAIGHT OUT from the middle. It'll eat up a good bit of time. If you polish in a circle, a fine hairline will ruin the disc. Go through all the rest of the grits as you would on a CA finish.
