Mix up your own perfectly matching wood filler in a disposable sandwich bag dispenser. First, put a couple of squirts of two-part epoxy into a plastic bag and add some sanding dust from the project (to match the wood). Knead the dust and epoxy with your fingers. Add more dust or epoxy as needed to create the right color. Protect the surrounding wood with masking tape, then nip off one corner of the bag and squeeze out the filler like toothpaste. Smooth off excess filler with a putty knife and let it dry to form an unshrinkable, rock-hard patch. Even better, you’ll walk away without epoxy smeared all over your workpiece—or your fingers!
