Same here. DIW takes a beautiful CA finish.
Me three... Just clean it with DNA or Mineral Spirits or some solvent first to get rid of as much of the surface oils as possible first so that it will adhere better.
My brother in law makes snooker cues out of iron wood. You really want to finish those with dozenS of light coats of spray laquer. But before all that you need to sand it to 800 clean with ethanol between grits.. maybe the translation is not working; but you say iron wood. That is mainly used for tool handles (at least here).. it is an extremely undesirable wood and nasty to work with. In fact, I made a work bench top from siam iron wood; it just sits in my garage because it gives me a rash if I touch it.
It is pretty expensive here as well. I am not sure if we are talking about the same thing; the "Siam Ironwood" is nasty stuff, first time I messed with it I got a splinter that was like a broken syringe in my hand. It looks good; and it can be sanded to a mirror finish; but on a lathe its like a bundle of needles.
