In one sentence, describe what the following article is about: Put wood filler onto any scratches or holes that might result from removing gum. Smooth it out with a putty knife until it feels smooth to the touch. Drying on a small area may take a few hours. Allow the filler to dry completely. Choose a wood filler that is paintable/stainable. With a fine grain sandpaper or an orbital sander, rub the area until it's very smooth. If you sand it, and it's still not smooth, reapply wood filler and sand again. If the surface will be visible, be careful to limit your sanding strokes. Once your surface is sanded smooth, you may paint or stain if desired. If the surface needs only light repair, a wood oil may be sufficient. Generously apply the wood oil to the affected surface with a brush. Allow to soak in for 30 minutes, then rub off excess with a soft cloth. Applying the oil along the wood grain will work best. Tung oil is good for tables on which food may be prepared, as it's non-toxic. For outside tables, Danish oil or teak oil is recommended. Furniture polish may be used following application of oil. After table has been allowed to thoroughly dry, spray a soft cloth with furniture polish. Spread liberally across the table's surface. Furniture wax may also be used. It requires more effort to apply, but results in a more stable surface. Furniture spray contains silicone, and will have a brighter finish than either wax or polish. Buff well to bring out the most shine.
Summary: Use a wood filler. Sand the area. Apply a wood oil. Polish well.
