I have used ureshell and sculptorcoat both
2-Part Urethane, Hard Shell Foam Coating
UreShell is our latest offering in fine foam coatings. UreShell is a marvelous hard-coat, 2-part, urethane-based coating. Its average 25-minute pot life allows for rolling or brushing. Applications cover both interior and exterior surfaces. It leaves a hard, glossy, smooth shell finish. It works great on props, backdrops, signs, molds, etc. One gallon covers approximately 320 sq. feet at 5 mil thickness. Dries to a tan color and can be finished-coated with most all paints and synthetic stucco.
sculptorcoat
A versatile, non-toxic, water-based plastic cream for tough, flexible coating, texturing and sculpting. Can be used as an adhesive, a sculpting medium, a filler or to add texture, and air drys to a clear or translucent finish (depending upon thickness of application). Useful for scenery and prop-making, tints, stains or dyes, as well as other textures (such as glitter, sand or sawdust, for example) can be added making Sculpt or Coat® an extremely adaptable artistic medium.
one neat thing about sculpt or coat is, if you need to paint it with spray paint
the paint will not flake off even if the part you covered with sculpt or coat
flexes.
I was pleased with both products.
