You could try Minwax wood hardener, but I did a few tests with it on this channel and decided that it doesn't work all that well. But it seems to be a product with a lot of fans and supporters if the comments I got were any indication. But if I was trying to preserve anything porous like rotted wood today I would try some kind of thinned out marine grade epoxy.
Nice job. That looks really good.
Do you have any recommendations for hardening rotting wood I've never had a Reason to but I'm trying to preserve an old stump
