Query: This product will RUIN your discs!

I used this product, and, yes, I followed the directions. The first step of sanding down the disc left a thin white residue and a lot of tiny scratches on the disc. The second step has you buffing the tiny scratches out. Most of the scratches seem to disappear when you look at it, but once you put it in your DVD player, the laser won't read it. I tried buffing it VERY smooth, and also cleaning my DVD lens. Still didn't work. I have to send my DVD to skippydisk to repair the damage done by this product.If you look at the reviews, there is about a 50/50 chance that you will get it to work. Is this any kind of indicator as to what kind of company this is? I think so. Too bad I was in the half that couldn't get it to work...
