You cannot get Alumilite white or any of the rigid Urethanes to the density of cedar or balsa with any amount of microballons. You can get the density of Maple if you add an equal volume of microballons to an equal volume of the rigid urethanes. If you added anymore microballons you could not pour it properly.
If I want the density of cedar I use Alumifoam which is the same density and is tough as an anvil.
If I want the density of Balsa I use 610 foam which is the same density and about the same strength as balsa.
I think my bucket list has a hole in the bottom!
