## Questions & Answers

**Q: Can you press dents into this with your fingers once it’s fully cured?**
A: If you pour too much, too fast, you can create less dense regions that you can press your finger into. If you are patient with your pour it's pretty dang rigid - with that being said, if you put a tremendous weight through your thumb, you can still dent it a bit, but it's not easy to deform (I'm a 180 lbs male of average strength).
