freshly applied urethane adhesive.

CAUTION: Insufficient curing of urethane adhesive may allow

unrestrained occupants to be ejected from the vehicle

adhesive from the window surface by using a clean utility knife or razor blade scraper.

3. Inspect the following components for the causes of a broken window:

The flange of the window opening

The window reveal molding

4. Inspect for any of the following problems in order to help prevent future breakage of the

window:

High weld

Solder spots

Hardened sealer

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.

Do NOT physically disturb the repair area until after these

1. Remove all traces of broken glass from the outer cowl panel, seats, floor and defroster

ducts.

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.

6. Verify all primers and urethane adhesive are within expiration dates.

IMPORTANT: 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
