It's pronounced "Fronkensteen."
Mine are all painted with Monster Mud, or more recently just Original DryLock. I think the Stucko could work, I think you would still need the Drylock or exterior paint to Seal it. The Plywood core gives them sufficient weight to not blow away. And the rods are a fairly snug fit in the tubes, so while not a problem to remove, It would take alot of wind to lift them up. I actually have problems with my bigger props falling over, not my tombstones.I have always worried about when I start making them that if they did get blown around, since they are foam they will get damaged. Could that stucco material be painted on the outside before they are painted prevent that?
