I love and use a lot of Tru Oil. but if you are going for a high gloss table top look, it takes some effort and is not neccesarly easier than other finishes.
On the BC filler / sealer, it works, but I was less than impressed with it. The way it smells and acts reminds me of airplane glue. As a filler, it was fiddly to work with and takes several coats and has a lot of initial shrink back.
For grain filling, I wet sand with strait Tru Oil and some 400 grit, it creates a oil / wood dust slurry. Depending on the wood you are working with, it can take a couple sessions.
Although it takes some effort, I go this route over other fill methods for consistent even coloring. I think that Tru Oil just looks better on bare wood than other product.
Once filled, I build up some body and wet sand / block it down with some 1000 and mineral spirits, rinse and repeat as necessary till you get it all built up and level.
I then spray a couple last coats, wait about a week, then rub it out.
You can buy Tru Oil in a rattle can or thin it for spraying, 2 parts oil to one part mineral spirits works well for me in a small detail gun.
Here are a couple pics that show the result.
