Sanding between coats of paint or lacquer?

That's a dazzling finish.

I think the real secret though is in the abrasives rather than the spray lacquer. Micro Mesh abrasives for example will reliably and consistently deliver mirror gloss surfaces on all sorts of finishes, from pu varnish to epoxy.

Still, none of that changes the fact that you've produced an amazingly sophisticated surface, so congratulations!

Congrats, that is absolutely top notch!

that's a very high gloss, almost looks like it's been french polished, nice job
