Oiled finish - advice appreciated

[Peejay]

How do all

 

I've just got hold of a really nice German made Adler PJ body from @Aidan63 (top guy) that I plan on using as my first bass build. There isn't a massive amount of grain in the wood but enough for me not to want to cover it with paint, so I'd planned on an oiled finish. I've never done this before (or built a bass either) and don't want to screw it up so would welcome any advice that's available. 

Having read lots of articles there seem to be several alternatives - Tru Oil, Tung Oil and others - and I'd rather not have to apply nitro lacquer on top if at all possible, so I'd greatly appreciate guidance, whatever is available.

Also, what other materials will I need, including grades of sandpaper?

Cheers
