Some automotive glass has clips, tabs, or nuts that will
restrict the removal of the glass. Once the Invisible
Heat has released the urethane, outward pressure will
pull the window away from the frame, with these struc-
tures intact.
The Process
Beginning at a corner, heat and release a section of 6
to 12” initially. Using the plastic L-wedge, place the L
portion of the wedge behind the glass, hooking onto
the window to allow leverage and slight outward pres-
sure on the glass. Once the metal reaches the opti-
mum temperature the urethane will release from the
metal within seconds, the urethane will begin to smoke
and crackle. At that point, begin to move the attach-
ment head around the glass perimeter where the glass
is bonded to the pinch weld at a rate of roughly one
centimeter per second.
Once the initial release of the glass is achieved, con-
tinue to move the attachment around the remaining
window perimeter. Continue to use additional wedge
for continual outward pressure on work area. NOTE –
you may use water or Inductor thermal gel spray to
protect paint from possible overheating.
Once the urethane is released, it won’t re-adhere, so
keeping the released portions of the glass separated
from the pinch weld is not necessary. Placing wedges
around the windshield will just add more pressure on
the glass, increasing the risk of breakage.
Occasionally when the window is removed, some paint
may be attached to the primer and e-coat, other times
the paint will be attached to the urethane and the e-
coat on the pinch weld. Either way the pinch weld is
clean and free of any urethane adhesive.
