Slip Plate/Dry Moly Application

[OL JENNY]

Les Andrews in his book, and some others on the Barn have talked about applying Slip Plate like products to the BOTTOM surface of each leaf if you are refurbishing Model A springs. Does it work better when only applied to one surface as opposed to applying it to both the bottom of a leaf and the top of the leaf below it? Is there a disadvantage to doing both surfaces?
