I think it might be great for using as a "base coat" (diluted, of course). I got some LMF stains recently, but I wasn't happy with the darkness of the colors I'd chosen, so I put some of my grey-black vinegar and iron stain on a scrap then some LMF. The results show a much darker color, lots of figure and make the stripe pop out better than the LMF stain alone. The ebony toner used as a base (probably needs to be thinned) might work in the same way in addition to other uses.
