<speculation
Unless you had something blowing the molten solder out of the holes,
I'd expect that the solder would wick into all of the holes. A wave
solder machine fills the holes when there are leads present. Without
the leads, I'd expect that to still occur.
Without solder mask, I'd also expect you'd get a lot of shorting of
adjacent traces even with a very wide separation between them.

Somebody makes a chemical solution that does what you're looking
for. IIRC, it's called 'Tinnit'.
