David ★★★★★ Oct 22, 2026

I was a bit skeptical about the 8 oz size, but it’s actually perfect for small jobs and doesn’t take up much shelf space. The liquid activates exactly as described, and the medium consistency spreads evenly without any mess.

Emma R. ★★★★★ Oct 20, 2026

Picked up the 8 oz bottle first to test it out, and it's handled a few medium-duty jobs without me needing to reapply as often as I feared. The container pours clean with no drips down the side, which I appreciate. Glad I went with the smaller size since a little goes a long way.

The quart size is perfect for my frequent projects, and the activator itself works consistently every time I use it. After trying a few other brands, this one just performs better without any fuss or residue.
