Yeah, a penetrating hardener does help greatly.
There are several custom acoustic builders that use water-thin CA as their sealer/pore filler/wood hardener of choice. It works especially well on the soft cedars commonly used as tops on classical guitars. It penetrates and makes them much more resilient, without detrimentally affecting the tone. The really great plus with CA is it cures hard pretty fast, so production does not have to stop while a finish cures. I've tried this and it works, but the super-hard surface that results does require a different approach to level-sanding the parts.
Other makers have adopted UV-cured penetrating sealers for the same reasons. I tried UVs, but the increased cost does not make it worth using for me because I'm not a production shop and I have the luxury of time.
