Pasting happens naturally. Once you have worn out a few strops you will understand. Your first "pasted strop will be one coated with ferrous oxide. Thats the residue your razor leaves behind on a virgin strop. You will notice that over time your stop darkens. That is the residue from your razor. Time will age this into ferrous oxide. In days gone by to protect the blade from rust graphite was or lampblack was added to the strop for protection and to extend the life of its suppleness.
In another 5 years you will wear out another strop and another genius idea will hit you, and ....you get it.
Just hang in there. Give it about 10 year or so. :)
