anybody having the same issue I have with getting a super smooth finish. I got 2 coats of sanding sealer and three coats polycrylic on a table. always somehow I still get those little specs of what appears to be dust particles landing on the wet surface. Just a few but enough to notice. Can these be buffed out? what would be the procedure?

Sand between coats and sand the final coat until smooth. Basically you need to polish by sanding with successive grits and buff if you want. Sometimes people will wipe on a thinned coat for the final if they want a shine.

I use wet/dry sand paper 220 for the first coat of polyurethane. Then I move to 600 for the next several coats. I also try to make sure to reduce air borne dust to the minimum. Sometimes I will use a tack cloth to wipe any residue off the surface. Then for the last several coats I use a piece of polyester cloth folded in a rectangle wrapped in a piece of panty hose. These don’t leave any lint. I thin the poly to almost water and using the cloth I can move the poly like a squeegee and by playing the light I can get a very nice smooth finish. the most I’ve ever done is 12 coats. It’s like glass.

“Let the waterborne fully cure for a couple of weeks. You can then “rub it out” just like any finish. Use mineral oil, mineral spirits or water as your lubricant”.

The above advice was stolen from Howard Acheson, a well known and respected person in the woodworking circles. He knows his stuff.
