José's client wanted an organic, wood-grained look for their glass spa doors. His solution was to take the texture of a log right from the beaches of Puerto Rico using Equinox Silicone Putty!

Free Form Habitat Black Epoxy Putty was then applied to stainless steel door handles, sculpted, and textured using the stamps for a realistic wooden handle.

Weston Brownlee and his team created the tree featured in the new Netflix series The Boroughs.

The bark texture and canopy of the tree was constructed using KX Flex flexible urethane elastomers and Feather Lite ultra-lightweight resin.

The dazzling quartz crystals were rotocast in Crystal Clear resin to reduce weight.
