I just put down 2 coats of Bona Traffic HD (with a buff in between). Looking at the floor that are a couple of areas where the finish is higher than others (not much, looks like a little "puddle").

Question: Can I sand that area down with a light grit (400? 600? 800?) without changing the appearance of the sanded area?

It may be impossible to match the gloss level of the adjacent floor without adding another coat of finish over the whole floor.
