Hi, Bob. I'm not disputing Jay J's comments at all and if the gouges are small, I would not bother with them. But I will offer another alternative and it's suitablility king of depends on the stain color of your floors. Minwax does make a two part wood filler that is kind of like Bondo, if you have ever used that. It mixes to a light wood color and if you put a stain over it, it accepts the color but not as well as wood does. So the secret is to stain, apply one coat of poly, let dry and lightly sand the floor, clean up the dust, restain just the filled area with a small brush and let dry, then apply another coat of poly. Then you can go through the sequence for as many coats of poly as you wish or until you can no longer see the color variation. This worked great for me with an oil based poly. You can not see the color variation unless you really look closely.
