The Birchwood casey sealer filler, which I use extensively has got a pretty powerful solvent content, so I suppose its not impossible it might pick up a little bit of the stain. It wasn't an issue on my mandolin though. In any case as you've got a single colour instrument I don't think it would be an issue, since what you move one second will be back the other. When in doubt always do a test piece of wood:-)
