Surely there is some source of fine buffing powder less costly than this product. The paste came in a tube about the size of my pinky finger and even at that was only about half full.

I managed to buff out a scratch on my watch so it looks like new except for the fact that the plastic is now slightly concave. The change in shape is very subtle, however.

It took maybe 20 minutes and half a tube to get the scratch out.

I then tried the stuff on an eyeglass lens scratch on a drugstore pair of magnifier glasses ($15 plus tax, so expendable more or less). I now see why "eyeglass lens" is never mentioned in such ads.

After about 30 minutes of buffing (used up almost all the rest of the compound), I got rid of the scratches only to get nice smoothly wavy depressions in the glasses that distorted the lens far more than the original scratches. So ... never use on anything you need to look through, just on lenses you look at.

Anybody know a source of the type of buffing compound used in this product?
