I remember this being discussed before, but I can't find the thread. I have some Wenge, which has cracks that are a part of the make up of the wood. Superglue is just not filling them the way I want. Someone mentioned a wood treatment that could be found at Home Depot and other such places that fills in cracks good.

Anyone know the name of this stuff?

Ya, I can't think of what it is called either. I think Dembart wood finishing makes what you're looking for though.
