Plastic and Foam Experiments

I've been experimenting with some two-part plastics recently. My goal is to be able to create a relatively hard and smooth surface on carved foam props. Here's the results.

The candidates are both commercial plastic resins that can be mixed and poured easily. They have similar chemical compositions, I suspect, though they dry slightly differently.

QuikCast, available from TAP, dries white (about the same opacity as milk). Smooth-On, from Douglas and Sturgess, dries mostly clear. For my application the color isn't a big problem since the plastic will have color added to it.

The plastics were tested on three different types of foams to see how they'd fare.
