They all say that, but they lie. Every wood filler in the store says "stainable"... and they are, you can stain over them all you want, they just don't change color the way the wood does. So it is a lie..

What I mean is, you use the filler and it dries almost white, or off yellow. Then when you stain the piece, or use toner, it doesn't take the new color. The finish adheres to the filler just fine, but you can see the filler under it. So, you've got this beautiful wood with a new finish and a white splotch wherever you used filler. It doesn't reject the top coat, or cause a huge fisheye or anything like that... it just doesn't accept the color well. Toner is very much just a tint, almost clear, so it is even worse than stain.

Try it out on a test piece of wood first. Smear some DAP on it, then spray it with toner and check the results. Since the DAP is walnut colored, it might work ok... but I bet it is like all the others... Just test it first and you'll see....
