Leveling water-based wood filler

If you've sanded down nail holes or dings which have been filled with water-based fillers such as Zar, Elmer's etc., especially on stained or finished surfaces, you know how long it can take, and the risk of leaving a light stop around the filled area. Next time take advantage of the fact that even though these fillers dry hard, they are not water resistant. A moist paper towel or rag rubbed across the spot will level the filler faster than you can sand it, and with much less effort. I wait to fill until after a coat of sealer so I am better able to color-match the filled area, using artist's oil pigments.
