Warning: Refer to Glass and Sheet Metal Handling Warning in the Preface section.
• | High weld |
• | Solder spots |
• | Hardened sealer |
• | Any other obstruction or irregularity in the pinch-weld flange |
• | The flange of the window opening |
Note: If corrosion of the pinch-weld flange is present or if sheet metal repairs or replacements are required, the pinch-weld flange must be refinished in order to restore the bonding area strength. If paint repairs are required, mask the flange bonding area prior to applying the color coat in order to provide a clean primer only surface. Materials such as BASF DE15®, DuPont 2610®, Sherwin-Williams PSE 4600 and NP70® and Martin-Semour 5120 and 5130® PPG DP90LF SPIES/HECKER 3688/8590 - 3688/5150 - 4070/5090 STANDOX 11158/13320 -- 14653/14980 products are approved for this application.
4.1. | Remove all traces of broken glass from the outer cowl panel, seats, floor and defroster ducts. |
4.2. | Clean around the edge of the inside surface of the window with a 50/50 mixture of isopropyl alcohol and water by volume on a dampened lint free cloth. |
Warning: Refer to Failure to Prep Primer Warning in the Preface section.
Note: Do not apply the black number 3 primer to the existing bead (1) of the urethane adhesive on the pinch-weld flange. Apply the primer only to nicks, scratches or the primed surfaces.
Note: Use care when applying glass prep clear number 1 on the window. This primer dries almost instantly, and may stain the viewing area of the window if not applied evenly.
Immediately wipe the glass primed area using a clean, lint-free cloth.
Note: The glass primer black number 2 is effective up to 8 hours after applying it to the glass. The primed surface of the glass must be kept clean.
Note: To prevent damage to the window due to objects impacting an exposed edge, upon installation, the window must rest 1 mm (0.040 in) below the surface of the sheet metal.
Note: Do not direct a hard stream of high pressure water to the freshly applied urethane adhesive.
Warning: Insufficient curing of urethane adhesive may allow unrestrained occupants to be ejected from the vehicle resulting in personal injury.
• For the moisture-curing type of urethane adhesive, allow a minimum of 6 hours at 21°C (70°F) or greater and with at least 30 percent relative humidity. Allow at least 24 hours for the complete curing of the urethane adhesive. • For the chemical-curing type of urethane adhesive, allow a minimum of 1 hour .
• | Partially lower a door window in order to prevent pressure buildups when closing doors before the urethane adhesive cures. |
• | Do not drive the vehicle until the urethane adhesive is cured. Refer to the above curing times. |
• | Do not use compressed air in order to dry the urethane adhesive. |
