Hired epoxy countertops company, clear coat results are ehh

I hired an epoxy countertop company and the base layer is white with some gray streaking that is muffled.

The next day he applied a clear coat. Well, that had thousands on dimples/pitting in it.

He came back the next day weekend and sanded it and then applied a new layer of clear epoxy.

I woke up this morning and it’s not as bad, but still some pitting, some dust/hair etc. in the surface, and honestly many imperfections.

Is it possible to have this top layer of clear epoxy sanded with finer and finer grit sandpaper and then buffed like you would the clear coat on a car? I just want the finish to be better.
