Elmer's P9891 Probond Stainable Wood Filler

DON'T purchase this stuff if you're going to use a clear oil-based stain on wood. I don't mind paying more for a product that works---but, this is paying more and and getting far less. I bought it because it said stainable--to me, that means it will assume its place as wood where you put it. No. The brad-holes were barely noticeable but because this gunk soaked in or made the area incompatible with oil stain, my eye is drawn to a pencil-eraser-sized bald spot around the holes themselves. The beautiful cornice box project now looks amateurish. My husband did a lot of carpentry in the navy---he bought cherry wood putty to use on these cornices, but I thought I knew better. I sure wish I would have used what he bought instead of this gritty product. It is dark out of the tube, gets darker when drying, then shows up in the middle of a stain-free area it creates. I hate to be wrong---I hope I save somebody the heartache of having a project ruined by this "professional strength" stuff.
