Step 6: Apply the glue solvent.
The spray smells like mineral spirits or something, but it basically liquefies the adhesive temporarily so you can slide the grip on. Then evaporates, leaving the grip permanently stuck.
The instructions are vague about how much to use, they just warn that over spraying could result in extended curing time.
I found that if I sprayed two squirts on one side of the shaft, flipped it over and gave two squirts on the other, and finally three squirts inside the grip, I only had about a minute of working time, which was just barely enough.
