I haven’t etched my first board, yet (getting asymptotically closer;
maybe this week if I can get my toner sorted) so I’m watching this
with extreme interest. :-)

I bought a container of MG Chemical’s “Liquid Tin”, Mouser part number
590-421-500ML. Once the board’s etched, you just swish it around in
some of this stuff and it tins the remaining copper. It’s supposed to
prevent oxidation, but it is not a solder mask. Mine came with a good
amount of precipitate on the bottom; anyone know if that’s normal?
