Wood, under some circumstances, can also be forgiving—like if you need to fill in a crack, nail hole, or a larger missing chunk. And that’s where wood putty and wood filler come in.

Epoxy wood filler is certainly a handy addition to any toolkit ... Epoxy's extreme durability can also make it difficult to work with: it will be harder to sand down edges or cut off uneven sections ...

If the panel moves even slightly, the putty breaks and falls out. Real wood, glued in place, should be more forgiving, and the repair should last longer.
