I stained the back of the guitar now and successfully achieved my two-tone look I was after. Unfortunately had some red stain bleed through the veneer, oh well.

I have started finishing the body with boiled linseed oil, and have done a bit of wet sanding too. It's coming up really nice, im quite amazing at how much of a difference wet-sanding .
Should I wet sand the top? (veneer) or leave it? I don't want to risk sanding through it.
I also realised that my kit came with a tone pot instead of a volume pot, so Adam is sending me out one, glad I noticed before I wired it up.
