Frank, I suspect that any sort of wax would come out of the pores as the leather is flexed. Wax tends to harden and crumble easily, and just doesn't lend itself to any sort of bending. Ron might be on the right path with the Plasti Dip if it will seal the pores from leaking light, without adding any significant stiffness to the pigskin. As for the shiney surface of the Plasti Dip, that could be a problem . . . I wonder if there is some sort of blace plastic sealer that yields a flat black surface?
