I tested the stuff extensively. It doesn't work for sealing like he advertises it for. And after seeing that he's still advertising it and selling it for lures he's about to get his first negative feedback from me too.
I got a refund but only after I hounded him for it. Not only did the stuff alligator on multiple coats, it doesn't harden like he says and it definitely doesn't seal any kind of wood I tried it on. I did some pretty scientific tests with it on 5 lures and it was a total waste of time, single and multiple dips, every one sucked in water and gained weight. Two coats on a painted lure and the stuff looked like crap.
snake oil for sure. They can't even spell polyurethane on the darn label right.
