Previously, we had glued styrofoam to the sign’s basic structure. However, the styrofoam needed to be hard coated before we could sculpt the rock over it. This involved pressing a thin layer of sculpting epoxy over the foam and letting it harden. We weren’t worried about getting things too smooth at this point, only covering the foam.
The final layer of rock was sculpted under the tires and we were careful to sculpt it at the same angle as the wheels.
Then it was time to start adding cracks and fissures into the rock.
Lastly, we used a ball of heavy duty foil, which we crumpled up to press into the soft sculpt to create the rock’s texture.
At this point, the old Willy's Jeep looks pretty dramatic perched precariously on the top of the rock.
