Mineral oil and wax doesn’t protect much. I was surprised. Maybe you need to get more oil soaked into the wood than I did, but I flooded the test piece with oil, let it get absorbed, repeated over and over until it stopped absorbing, then applied beeswax at least 2x. And it still stained easily.
I thought Waterlox would do better, and was surprised.
As far as I know, boiled linseed oil and tung oil are hardening oils, meaning after a (long) curing period they harden and become very protective. I didn’t test them because I don’t have the patience for multiple coats with several days curing between coats.
For the Emmets, I’ve been wiping on, rubbing in, wiping off excess, letting dry 8 hr, then very lightly sanding (like 400 - 600 grit) to take the slight roughness out (maybe it raises the grain? dunno), then applying the second coat. Similar for the Osmo.
