With the advent of both flexible and rigid fillers in recent years, putties have become less and less common but they still have a place. Glazing putty is still used when glazing wooden windows and doors, while woodfilling putties and other products like Selleys Plastic Wood are still available for a more traditional approach to woodworking.
One recent advent has been the introduction of two-part epoxy putties, the perfect example of which is Selleys Knead It. Knead It (which has a couple of different varieties) comes in a roll that allows you to cut off what you need and then knead the two components together to create a putty that can be used for a range of different tasks. Knead It cures to an extremely hard, durable finish and can be sanded, filed, sawn, screwed and painted when dry.
