What I find fascinating in this thread is that no one mentions the lack of working time you have with Tru Oil, It gets tacky and gums up so fast that you have almost no time to flatten it out in a thin layer. I cannot comprehend wet sanding with straight or even thinned Tru Oil for this reason.
The times I've used Tru Oil, I've thiined it with mineral spirits and added boiled linseed to slow it down and allow it to be applied in very thin coats. A little Japan drier helps to counteract the linseed's longer curing time.

The thinning of it helps slow down drying time. And also using it when fresh helps too. If it has started to thicken up in the bottle from sitting, then drying time is reduced when working with it.
When doing wet sanding filler coats, you don't have to work the whole stock at once. A section at a time is fine.
I rarely use Tru Oil anymore, but there are some jobs that it works well for.
