Query: Bad Idea

I thought this would help me remove old cracked glazing. No way! It did little more than rub it real hard. It was hard to control as well. Do yourself a favor and get a Dremel tool with a cutting bit. Or try a Rotozip like tool. You need one of these anyway! I have both and found the Dremel tool easier to control alowing me to quickly remove glazing. I also scratched the surface of the wood giving me a new wood face for the new glazing. Look at it this way. How much Dremel tool would the cost of this putty rubber pay for. I wish I had read these user reviews before I wasted my money.
