3. To prevent the product from clogging in the nozzle, do not allow the tip to touch metal surfaces during application.

4. For Thru Holes, apply several drops of the product onto the bolt at the nut engagement area.

5. For Blind Holes, apply several drops of the product down the internal threads to the bottom of the hole.
