I was walking down a creek on one of my neagari safaris, and I came across this portion of a hollowed tree trunk. It looks like it would make for a good base to create a penjing display. I usually see penjings on stone or rock, not anything like this. I think it would look cool, but I'm not sure how it would look natural as a small landscape, and of course I'm concerned about how I would treat it to prevent rot. I'm still learning about bonsai traditions and techniques, so any guidance would be appreciated.

I would first clean it, then use a dremel or so to clean the soft parts. Then do a bit of carving, or use a steel brush to further clean and deepen the grooves.
Seems Paraloid B72 is the best wood hardener to conserve it - it's used for restauration as well. I'm going to need something like that too, but haven't found where I can buy it yet (apart from ordering it online with relatively high shipping costs. I may order it, still).
Google Paraloid + bonsai for more info.
