  1. Remove dirt, grease, and moisture from surfaces to be bonded. Dry surfaces or allow surfaces to dry thoroughly.
  2. Cut nozzle tip to obtain desired bead size and PIERCE INNER FOIL SEAL.
  3. Working in sections, apply adhesive to one surface, 2" from edge in a zigzag or "X" pattern.
  4. Join parts immediately and wipe away any excess adhesive during application with mineral spirits. Do not allow excess adhesive to skin or over cure. Full cure time depends on bead thickness and other factors such as humidity and temperature. Higher temperatures & humidity accelerate cure time.
