Dave,
Not being a wood expert myself, I'd be hesitant about getting involved with this!
The biggest problem with wood is not knowing what's been put on it before.
You might struggle putting a metalised emulsion polish onto wax, it might not adhere properly, maybe it'd need sanding back beforehand. And if you're going to do that, there's a granwax liquid polish (dowding & plummer sell it) which brings it up a treat. Maybe give D&P a ring, you could get some sand screens for your rotary and have a crack at it if you're brave
