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.
