Leo ★★★★★ Oct 22, 2026

The two size options are a lifesaver—I grabbed the smaller one to test it out, and it's lasted way longer than I expected for my sanding projects. It kicks in exactly when I need it to slow the resin cure without any guesswork.

The 16oz size is perfect for my small projects since I don't use activator very often. It activates evenly without clumping, and the slow formula gives me plenty of time to position everything before it sets.

I needed a larger quantity for a big project, and the two size options made ordering easy. The consistency was perfect for a controlled, even application.
