I suggest spraying semi-gloss or flat aerosol poly over existing poly on a section of smooth surface to see if that would look ok if used on live edge. I believe stripping edges would require tank dip by a professional.

If the live edge has bark, then the possibility of the bark coming off is very possible. You might be able to reduce the sheen by steel wool-ing it.

Thanks, klem & sloyd. The idea of layering a flat on top of the shine had occurred to me but I didn't know if it would take years after the original finish. I'll try it on a flat so I can remove it easily. Thanks.

And sloyd, the bark is gone. There's just a *lot* of unevenness and nubs sticking out and I'm afraid if I steel-wool them, they'll either come off or get worn down. I like the immediate surface. Think I'll try the tone-down-spray idea and see how it works.

Thank you both so much!

I'd love to see a picture.

A thought for the live edge:
Pick up some of the darkest, flat, paint base and seal it with that. I also choose exterior for sealing properties. It goes on white and dries so matte you will wonder if you actually applied it. In areas where there are pieces you'd like to adhere, or make certain they don't come off (like paint chips stuff, for example) this seals it on without the goo-ed on look anything satin or shiny makes.

You can also pick up some matte finish varnish. Beautiful, Decoart, and General Finishes make them. Much more expensive than the paint base, though.

There are strippers that don't require steel wooling, nor protective space suits, etc. These are of the 21st century and offer pretty incredible results.

I'd love to see a pic of your new acquisition!
