The best time to fill nail holes in stain-grade woodwork is after staining. Filler never accepts stain like surrounding wood, so it’s best to leave filling until everything else is done. That’s where these putty pencils come in. Just rub the end over a hole, dent or ding until the depression is a little more than full. Gently scrape or rub away the excess and you’re done. Choose a colour that’s the same or slightly darker than surrounding stained wood for best results. This putty doesn’t shrink, crack, fade or smell. Made in the USA.
