DAP Plastic Wood Latex 16 oz Natural All Purpose Wood Filler Adhesive

I bought this to fill in gaps around the house, and it's been a lifesaver! It worked great for filling in rotted wood holes (make sure to take out all the dry, brittle bits first), for areas where you are fixing the work of an overzealous handyman, for those spots where you move the latch on door frames, and even for wood where the threads in a screw hole have worn out over time. Usually, I just needed to apply it, sand it down, and then prime or paint it. But if I'm fixing a screw hole (like I did on some hinges on the door frame), I find that doing that, letting it dry, drilling a pilot hole, and then applying a bit more before screwing in the screw gives the best fit. I also keep some wood epoxy around, but this is so much easier to use and usually comes out just as good. The only place where I prefer wood epoxy would be to fix high-traffic areas on floors or spots on door frames where the deadbolt has slammed into the frame and damaged that wood since it dries a bit harder than wood and reduces future damage.

I have been using this wood filler for many years on dozens of projects and repairs, and it works great. Very strong, easy to shape, easy to grind, easy to stain or paint. No way that it could be improved. Perfect as it is.
