Tru Oil is a nice finish and easy to apply. Rub it, wipe it, sponge it on, lots of ways to apply it.
It's not as durable as the finishes applied by the pros but works well for the hobbyist refinnisher like me.
Alot of very thin coats are better than thick ones.
I wouldnt stain the bow unless you just want it darker for some reason.
There are quite a few threads in this forum about the use of tru oil. A little research will give you lots of great tips for it's application.
Be patient and have fun,
