I use Pecards on my boots. I scrub with Fiebings saddle soap to help re-moisturize the leather and replace lost oils. Then I rub down with Pecards dressing. For waterproofing, I topcoat with Snoseal.

As I said, this is just what I do on my boots, it may or may not work on a leather pad. I can attest to the rejuvenating abilities of the combination of the Fiebings and Pecards.
