Can you press dents into this with your fingers once it’s fully cured?

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).
