glaze is basically thick primer in a tube - its great for deep scratches, chips, etc.
It dries fast, but it also shrinks and cracks if its too thick, so you want to do several layers.

My car chases storms, so I had to fill a few hail dents that way. They were too shallow for bondo, and I was on a budget.. lol
I have a ton of pics on facebook from start to finish that shows how bad the car really was. I don't think they will show unless your a friend though...

linky if it does work..
