INSTALLATION PROCEDURES FOR GLASS PARTS INSTALLED WITH URETHANE ADHESIVE
1. Remove all moldings, clips, windshield wipers,
cowling, screws, nuts, and bolts in the glass replacement area. (Note:
Interior moldings and headliner should be left in place unless specific
job conditions require removal.)
2. With a soft brush, vacuum or air hose, clean dirt
and road debris from the pinchweld area before cutting out the
windshield or other glass part and then again after it is cut out. This
step minimizes later contamination of the urethane on the pinchweld to
which the new adhesive is applied.
3. Cut the adhesive to remove the glass. Care must be
taken to avoid scratching the pinchweld. Once the glass is removed from
the opening, repeat step 2.
4. Dry fit the new part by centering it side-to-side
and by adjusting setting blocks (if so equipped) to get the correct
positioning of the part top to bottom. Make alignment marks with tape or
non-staining grease pencil on both the glass and the vehicle body.
5. Trim the remaining urethane on the pinchweld using
only the full cut method. In this method, most of the existing urethane
is removed leaving a level bed around the entire pinchweld approximately
1/16" thick. Again, employ great care to avoid scratching the
6. Prime all pinchweld scratches with the appropriate
Pinchweld Primer depending on the approved adhesive system being used.
Follow the manufacturer's recommended dry time for their primers.
7. Clean the inside surface of the windshield paying
particular attention to the ceramic paint area. Next, prep and/or prime
the inner surface of the glass on the outer periphery of the ceramic
paint with the approved prep or primer depending on the adhesive system
being used. Be sure to duplicate the path of the preps, primers and
urethane used on the original windshield. This is particularly important
along the cowl side of the windshield where the path may not be along
the outermost perimeter. Always follow manufacturers' recommended
instructions for appropriate dry time.
8. Use new foam dam if the vehicle was originally
equipped with one.
9. Apply a 1/2" to 5/8" high triangular
bead of a Carlite authorized urethane to the pinchweld on top of the
existing bed of urethane. The urethane may also be applied to the glass,
but care must be taken to ensure that the location of the bead will
match up with the existing urethane on the pinchweld. [Note: If the
vehicle originally had a double bead of urethane along the windshield
cowl, be sure to duplicate this.]
10. Install the windshield before urethane skins
11. Replace all moldings, clips, windshield wipers,
cowling, screws, nuts and bolts removed at the beginning of the process.
Test run the wipers after installation to ensure proper positioning.
Adjust positioning if necessary.
12. Perform a leak test to ensure that the seal is
complete. Ultrasonic or other methods may be employed.
13. Thoroughly clean both sides of the glass and
vacuum all glass and other debris from the vehicle. Run the defrost air
on high to blow out any glass fragments or other debris that may have
dropped into the defroster ducts.
14. Allow all glass parts installed with urethane
ample time to cure, taking into account temperature and humidity. (Refer
to urethane manufacturer's "safe drive away" time
recommendations and procedures for cold weather installations).
15. We recommend all Ford application glass
replacements be "Ford" or "Carlite" trademarked (
this is a requirement for Ford warranty work, Ford company cars, Hertz
& Budget vehicles, and Red Carpet Lease vehicles before turn-in).

approved adhesives for aftermarket use.)
