lacquer on new mando

Has anyone heard of a settling of lacquer on new handmade instruments. This looks like tiny little lines under the lacquer which you can feel. They run along the grain in short pieces for all the world like broken veins. Just looking for opinions before talking to maker. I vaguely remember a discussion on this before???

I think this can happen if the second coat of varnish is applied before the first coat is completely cured. You can also have a prominent grain problem if the wood has not been repeatedly wetted, then sanded flat after drying, as the grain reacts in the same way to the varnish as if it had been wetted.

I think Guernsey Pete has given the two most likely causes.
A third possible is that the first coat is likely to have been "thinned down" probably as a sealing coat and that has raised the grain.
It’s not unusual but the luthier should have cut/sanded/smoothed it down in between coats. caused by the two types of grain in the wood (summer and Winter growth) absorbing the coating differently.
