I noticed painting metal with auto paint that more coats meant more

measure of how thin the coat of paint was on tools in the store. No
soaking in on metal, I don't think.. Maybe something else at work..

More coats of finish mean more resin solids. As you build coats, more
resin solids mean a smoother finish as all the tiny, tiny voids and
imperfections are filled in, making the reflectivity of the finish
less scattered.

Seems like you would build voids at some number of coats?
