I just build a red oak book case. I have put on one coat of oil-based stain, and am planning on putting on a top coat of a different color oil-based stain/poly. It might be an odd combination, but the end result exactly matches the oak staircase it will be next to.
There are two small spots where the stain didn't take, and they are conspicuously lighter than the rest. (dark spots look fine, but light spots just seem to jump out) I have a crayon-like stick intended to be used on scratches that is about the same color as the stain. I am thinking about using it to darken the light spots before putting the top coat on; but am concerned the top coat might not adhear well to it, and it might be worse than not doing anything. (my wife couldn't see them until I put my finger next to them)
Any advice would be appreciated.
