Installation Procedure


    Object Number: 893679  Size: SH

    Important: Loose urethane and/or a rough surface on the remaining urethane may cause sealing problems during installation.

  2. Clean the entire window opening and glass bonding surfaces with a clean, lint-free, alcohol-dampened cloth.
  3. Notice: To prevent corrosion, paint damage around the window opening by the power glass removal tool must be covered with pinchweld primer. Do not prime over existing urethane. Follow manufacturers recommendations for drying time.

  4. For a new windshield only, shake the glass prep primer (Clear #1) well before applying. Apply the glass prep primer (Clear #1) around the entire perimeter of the glass using a dauber. Wipe dry with a clean, lint-free cloth.
  5. Specification
    The primer area, minimum width (A) is 18 mm (0.71 in).
