I used lacewood a couple of times 20 years ago or so. It was so light I thought it was balsa wood and you could easily score it with a fingernail,
I had the devils own time getting it sealed. never could get the pores filled. The more I put on the more the wood soaked it up.
It was discouraging and I still have a couple of pairs of scales left over from that time.
I'd try some tung oil for a base, following directions, then something that might build up a bit to top it off.
You might try carnauba wax melted on with the buffer. Get a cake of carnauba and apply it to a running buffer wheel till it builds up(you might have to jog the buffer to do this without flinging it all over the wall and you.
You then buff the handle gently at right angles to the grain till you get the desired results. You finish by hand buffing to even it all out.
Just a thought.
