A cheap natural bristle paint brush works well at getting oil into things like cornstick pans and waffle iron. Should do the same on pits.
That is an excellent idea! I will try that tonight with the next seasoning layer.

In my experience, if there is any rust at all on a piece, even if it's fairly superficial, that area, or the rust itself tends to absorb many times more oil than clean iron. It looks like you've got a little rust left in the pitted areas, not new flash rust. If you are generally okay with that, and are going to use it as a fryer anyway, I'd say just keep seasoning it, or better yet fry something, the deep oil will certainly give the rusty areas all the oil they want to absorb. After you fry in it, wipe off the oil to a thin layer and toss it in the oven to harden up everything.
And remember, fried food is better with friends!
Heat some lard, like you were going to cook fish, and let it cool. An inch in the bottom will do the job. If pitting is also on the interior walls, use a wood spoon to spread the lard. Let cool and wipe out the lard with paper towels or soft cloth. Small amounts of lard will remain in the pits. Reheat and wipe until all lard is gone.
