Where do I go from here?

All I have used is PolyU, which isn't good enough off the brush. While the reflections are very sharp, it always has small pinholes & ripples not matter what. But sanding & using something like eee ultra shine only looks reasonable on low angles & from a distance, but up close the reflections are fuzzy. I tried waxing. Looks bad. I want something with the wet sharp look of off the brush but perfect mirror flat from sanding & cutting. Does canned shellac after sanded & cut have the same problem of reflections not being sharp enough? Thanks
