Here's a guitar body I finished with Tru Oil. Like @Gilmourisgod said, THIN coats are the way to go. This has 8-9 coats on it. I waited 24 hours for each coat to dry then sanded with progressively finer sandpaper (starting with 220 and ending up with 2000) between coats. After the final coat dried for a few days, I hit it with 0000 steel wool then polished with automotive polish. It's very hard and not sticky at all.
EDIT: The neck has 4 coats of Tru Oil on it, but I didn't polish it, so it has a satin finish.
