Does anyone know the best way to repair a quarter inch wide chip in a table top with a heavy oil-based satin polyurethane finish? Chip is not all the way down to the wood, but through most of the coats of finish. Any suggestions short of sanding down to the wood and starting over? Thanks, Glendo.

Hey Glendo,
I don't know if any way is the best way - are you familiar with burn in sticks. This may be a good place to use a material like that for fill in repair, -

If you're willingly to live with a bit of halo around the repaired area, you can likely just clean out the chipped area with an appropriate solvent like naphtha and then "dob" in some poly with a small artist's brush to a slightly overfilled state. Allow to dry for at least a week and then carefully wet sand to flush. Rubout surrounding area as well with whatever you originally did. You will however, have that little halo around the repair that will show when the light shines across the spot.
Edit: I can't see the piece and don't know if this is appropiate, but...you might also consider placing some colored epoxy (a bit of stain or ? mixed in) in the chipped area making it look like a small knot or other infraction in the wood.....rather than using the clear finish as the filler. Make sure you immediately poke out any air bubbles when you place the epoxy.
Knowledge is power, but only if applied in a timely fashion.

I believe you could use a clear burn in stick to fill the chipped area. When you melt the stick you must use as little heat as possible to prevent the formation of bubbles in the filled area. The whole piece will then need to be scuff sanded and coated with one or two coats of polyurethane. Finishes such varnish and poly, don’t fuse together between layers making repairs to only one section almost impossible to disguise ( at least I’ve never had any luck). One other trick would be to fill the area as described, and use padding lacquer to coat the whole surface, hiding the damage. There are so many variables with regards to compatibility, that I’m not sure my advise will work, but it is what I would do if this were my problem.

Thank you for all your replies. I believe I'll try repairing the ding with varnish, as the stain is still intact. Looks like this is going to be just as difficult as I thought! Oh Well! Thanks again, Glendo
