....MinWax wood hardener is easier, and perhaps a bit better at penetrating and sealing than CA....
The thoughts are with epoxies which I generally agree with, but I have used this product and am pleasantly surprised by the results. For nonstructural sealing, I think a quality ultra thin CA has the edge in wicking end grain penetration. Plus, the needle tip is very convenient for occasional use with minimal worry of misapplying. I checked a few hand tool handles that I soaked in the wood hardener about ten or twelve years ago and they have held up well, minimal dents, swelling or shrinkage at metal connections and no end grain checking.
I recall completely submersing them for a few days, there was a ring of penetration, but certainly not through and through. Plenty enough though, I stood a couple of them half in water and didn't get swelling that I could measure after a couple of days. All and all a good product that's easy to come if it fits the bill for the job at hand.
