Doesnt spray out well, just drops down, doesnt expand. I don't know if I had bad cans or what but garbage **Q: Is this water proof?** A: The can is labeled "water resistant." **Q: Is it waterproof** A: Can’t say if it is waterproof or not but if you get it on your hands you will wear it for a while. I tried various solvents to no avail. Wear disposable gloves. **Q: Can I use this around a gas pipe?** A: Rigid or Flexable copper/brass? I have to fill a gap between a wall and cabinet where the pipes run. ## Customer Reviews ### ⭐⭐ Defect products *by M***I on 20 July 2022* Cans I received seem old and the form materials hardly came out.
