One thing that does seem to show through the clear topcoat is what I call a 'quark'.

Whether part of the original bare wood covered in clear or on the surface of the color coat, a piece of debris that has been riding around stuck on the front of your sanding pad ( on a reciprocal sander ) will jump out at you much later. Admittedly a bigger problem on the surface of the wood, as a color coat with a common solvent to the top coat will tend to melt or marry together and may obscure it.

Sanding can cause more grief than benefit, unless you have time to set the work aside a long long time. Modern 'lacquers' skin up fast, whilst staying gooey and rubbery underneath; once you penetrate the skin surface with the sanding paper, the gummy stuff underneath can be freed and become a pile of 'marbles'. Note all the isobutyl alcohol in the contents lists of these products. Makes me wanna get a compressor and blend my own lacquer to get that harder finish.
