Question
After sanding the finish to eliminate some water rings I applied some Polyurethane (gloss) to bring the finish back to the original shine.  But the finish remains dull.  What would cause this and how do I fix it.  Thanks

Answer
Hi Marvin, what type of wood?...it's likely that since you've only applied one coat, it sank int the wood, and you'll need to "build" the finish with a few more coats. The real issue I see is that you're most likely working with a lacquer top, and you can't use polyurethane over lacquer. Also, sanding is not the way to do a repair of this nature, unless you're using very fine grits and attempting to feather in a repair using the correct finish (i.e. lacquer} If the rings were only n the finish, and the finish was still smooth and intact, you should have tried to chemically remove the rings with Blush eraser, a chemical solvent release agent in an aerosol can. You will never be able to blend a spot repair done with polyurethane with the surrounding lacquer.....they just don't play well together.Lacquer repairs need to be done with lacquer. Post back - regards- Greg
