Elmer's Carpenter's Color Change Wood Filler, Natural, 8 oz

This is a good product. Its a small container. Bigger is better! So get the bigger one if you plan on doing a lot of filling. By a lot I mean I did three door hinge holes and about 6 cabinet small cabinet knob holes and isn't much left. I will go bigger and buy it again.

I do a lot of 3D printing with PLA filament mainly and before painting the terrain features, it is often necessary to get rid of ridge lines and such using the Elmer's Wood Filler. I have some very large structures, and so it can take a while to cover them with the Wood Filler. I purchase the small containers because once it starts to turn dry it will turn color. If you have a large container the catalyst is in the filler that is invariably going to dry, and if you don't use all of that large container, then a lot of it is often wasted. If you purchase a bunch of the smaller ones, then far less is lost, and usually you can pace your work for your models by using a jar at a time. This approach has worked well for me.
