The SI Flaks I bought a year or two ago came with the little pen to reapply the coating. I noticed it brought them back to nearly original condition to where they'd resist water and oils and they'd clean up so easily.
I used the same pen on other lenses without as much success. They required frequent applications as I think any time you wiped them off (often for me) it would remove the nano clear. My pen dried up and I didn't plunk down the cash for the kit.
