Finally, a release agent that actually works between cured silicone pieces. The brush applicator makes it easy to hit every detail on my two-part molds, and I haven't had a single stuck seam since I started using it.

Benjamin S. ★★★★★ Oct 22, 2026

Brushed a thin coat onto the seam of my two-part mold and it peeled apart perfectly with no tearing. Definitely makes complex castings way easier to pull off.

Two fl. oz. went further than I expected, and one pass with a brush was enough to keep the halves from fusing on my latest mold. The release didn't leave any oily residue that messed up the next pour, which is exactly what I needed for the more complex casting I was attempting.
