Thanks for the tips guys. I really thought this thread might go in two completely different directions based on my two questions. Am I correct in thinking both questions might have the same answer?

The only thing I've stained in my life involved beetroot and a t shirt, so while it sounds simple, this is new ground for me. Any tips for choosing the right one in the store?

Simon: I've seen too many build diaries where glue was an issue, and I think in most of them you tried to warn the poor individual struggling with it. Point definitely taken on that one!!

I don't really have the space or means to spray anything, so that'll dictate the application I go with. I've noticed a lot of good instructional posts and online articles about applying a finish, so I'll try not to bring out too many stupid questions, but those^ should bridge the gap between "Finish? WTF??" and the point where most other instructions pick up.
