I've used MinWax wood hardener. Works fine. Seals quickly and dries nicely. I use it to stabilize fungus woods but it can make a finish all by itself. It is easier to work with than CA and seems at least as tough. In another hobby, we discovered that Plexiglass melted in acetone (takes a day or two to melt small shreds) makes a good substitute for MinWax. An auto tail light cover that has been shredded works, too.
