- Clean and degrease the surfaces, roughen smooth leather.
- Brush a thin coat on BOTH parts and let it dry until it no longer feels tacky (about 10 min).

Holds: we recommend it
With surface treatment: holds only after you treat the surface first, the note in the cell says how
Not recommended: our glue won't bond it
A contact adhesive is applied to both parts, so it has to suit both materials.
