1939 Packard SIX Leaf Springs

I am in the process of replacing the 6 leaf spring bushings on my 39 Six. Since it will be a quick task to remove the springs, I plan on taking them off, cleaning them and painting them. I noticed what appears to be remnants of some material between the leaf's. What is that material and anyone have a source for it?
