SC6000 Leather Protectant for Books
This is a half ounce trial size. Be sure to keep the container sealed thoroughly because SC6000 will dry out and harden if exposed to air. You can put a bit of waxed paper inside the container to be even more thorough.
SC6000 is good for abraded areas of leather to seal and protect them. Use after applying the leather consolidant: Klucel-G. It is also good for sealing Japanese tissue repairs on corners and along board edges.
