My dad is working on something that he needs some Den-Shield and he asked me to go on the net and find some stores that stocked it. Well, I am not the computer whiz here, but I can get around on the net a little better than my father, I mean he just learned how to turn it on the other week. I would great apprechiate some information that could help me find some stores that sell Dens-Sheild. I live in the Downingtown area (near Philadelphia) my zip code (if it helps) is 19335. Thanks very much. Hope you have a good day.
