    I am prototyping a flexible water compartment using the Elastoplastic. Since the elastoplastic material is porous, I was thinking about using a "liquid latex" to coat the interior surfaces to seal it and maintain the flexibility of the part.

    Has anyone done this or have any concerns about doing this to the part? What other ways can you think of to do this?

    IME that material is pretty crappy, breaks easily. Not sure how it might react to 'liquid latex' or if that will buy you any durability. You may want to look at making a mold and pouring urethane or vinyl parts. -S

    You might want to make sure that liquid latex doesn't dissolve in long term contact with water before applying it to your limited edition elastoplastic print, considering the material is no longer available from Shapeways.
