Surface Preparation: Prior to application, clean surface of all dirt, loose paint, rust, oil and grease. Allow surface to dry before applying sealant.
Directions for use: Once all areas have dried, cut nozzle to desired bead size and puncture inner seal. Using a standard caulking gun, apply bead at a 45 angle using constant pressure. Use at room temperature for ease of gunning. Tool or join surfaces for sealing before material skins. Support tooled or joined surfaces for 8 hours minimum. Use mineral spirits to remove excess material before skin forms.
