When gluing wood some of the glue gets on areas that are to be finished. This tends to seal the wood so that the finishing stain doesn’t take as well in that area causing it to appear lighter than the finish elsewhere.
What suggestions do you have to prevent this?
I’ve tried skimming off the excess glue with a chisel. Is it practical to apply the finish before gluing?
Any suggestions would be appreciated.

Bob;
I use a water based glue and keep a damp rag on hand when gluing. I wipe off the excess glue before it dries. Some prefer to chisel the glue after it has cured but it seems like the glue penetrates and seals the affected area. I always sand the entire piece just before staining so the raised grain from the water wipe is removed.
If you're using a different kind of glue you may be able to use a solvent to wipe off the excess before it cures (unless it sets very fast).
*I remember reading an article in one of the woodworking magazines last year by someone telling about wax finishes. One thing he did was wax before gluing. Any squeeze-out would pop right off the waxed surface after it set.I question whether you could do that with a penetrating finish. It might penetrate right to the glue surface and prevent glue adhesion in the joint near the finished surface.How about masking tape? Overlap the edge, press firmly to the wood and trim to the edge with a razor knife before gluing.
*Becareful on using tap water on certain woods the iron in the water can discolor types of woods like cherry.I use a cabinet scaper to clean up any glue. If your going to use water use distilled water to clean up the glue. Then to check for showing glue lines use the same water or naptha Good luck
