Eventually, every home will have some damaged wood. Perhaps it’s a porch column with a little water damage, or a door jamb that had an ill-timed meeting with a piece of furniture being moved.
For minor damage that isn’t a structural issue, one of the best repair solutions is to fill the gap with automobile body filler. While normally used to repair dents and dings in a car, it makes a great filler for any wood surface that is painted.
The two-part epoxy bonds quickly to the damaged wood surface. It hardens within minutes, and once cured, it can be sanded smooth, primed, and painted. Automobile body filler should only be used for cosmetic repairs, but the beauty of the product is that the damage that was once an eyesore is now completely invisible.
