Enhancing endorsement?

[eleet]

I recently acquired a Tris Speaker endorsed glove. It has nice black leather but the endorsement is difficult to fully make out. Speaker is visible, but the Tris is worn off. The easiest part to see is the "ker" with the rest of the Speaker more difficult to see. I know there is nothing to do about an endorsement that has completely rubbed out (like the Tris part), but is there anything that can be done to strengthen a weak one? Thanks
