Directions for Use
  1. Always apply over automotive primer. Applying over bare metal will not provide enough corrosion protection. Acid etching primer is not recommended; if used, be sure to allow to fully cure before applying seam sealer, or residual acid can weaken the bond.
  2. If necessary after priming, clean and dry surface with 3M™ General Purpose Adhesive Cleaner, PN 08984. Do not use an adhesive cleaner until the primer has fully cured.
  3. Install foil package into barrel of 3M Flexible Package Applicator Gun, P.N. 08398.
  4. Using a scissors, cut a small opening across the top end of package and fold back flaps.
  5. Place nozzle over the opened end onto the gun barrel.
  6. Replace the retaining collar.
  7. Cut nozzle to provide desired bead size.
  8. Apply seam sealer and tool (if necessary) to desired finished appearance. Alcohol solvents will not stop the curing process.
  9. The product is immediately paintable. If tooled with solvent, allow solvent to fully evaporate before painting.
  10. After use, dispose of both nozzle and empty package.
