Brian ★★★★★

I was surprised how little pigment it takes to get a vivid color—just a few drops turned my clear urethane into a deep, opaque red. The black is also incredibly dense and covers evenly without any streaking. Perfect for small casting projects where you want bold results.

George T. ★★★★★

The purple pigment made the urethane foam look far more vibrant than I expected, even at just a few drops. Blending a bit of red with yellow was easy to mix into the rubber for a custom orange.

James W. ★★★★★

I’ve been using the white and beige to tint foam for a small casting project, and the color stays true even after the urethane cures. The UV resistance is a real plus since these pieces sit near a window.
