COATING ON TOP OF GLASSCAST 10/50

My current project is taking a beautiful but rough, uneven, full of defects burl of hardwood and making it into a table top. It’s odd-shaped and, as I want the top to retain that odd shaped, surrounding it in a dam wasn’t possible. I used GlassCast 10/50 in several layers to fill the many voids. That’s been successful although, after sanding, there are some parts that are back to wood whilst most have a coating of resin so that the top is even enough to function properly. I now want to finish the top. Any kind of self-levelling product would just fall off the edge. Ideally, I’d like a satin finish and, if this were a normal wood-only top, I would use a brush on wax-oil or, if I wanted a better finish, apply 2 part lacquer with a sprayer.

Is using 2 part lacquer preceded by lacquer primer going to work on top of the resin? Will I be able to see the difference between the lacquer-on-wood and lacquer-on-resin areas?
A couple of the voids go right through the piece and I have polished these so that it is clear. I have doubts about the lacquer adhering to these areas. Am I right and, if so, what can I do?

I could take another piece and trial all of this but I thought this must be a challenge others have faced and beaten.

Thanks
