For some reason epoxy over pu feels super soft and dents easy. Surprised this don’t happen with poly or eps boards.
the reason why epoxy dents more over PU is because it is a more flexible resin than polyester (which explains why polyester resists denting more).

The reason why epoxy dents less over EPS is because EPS is a lower density foam (typically) than PU. So with a lighter EPS blank there is more left in the weight budget for a heavier glass job. The extra glass and resin then stiffen up the laminate.
