Use the short method where the original urethane adhesive bead left on the window opening pinchweld flange (after window removal) can serve as a base for the new window. This method uses a small bead of urethane adhesive in order to adhere the window in the opening to the original urethane adhesive bead.

Use the short method when the original bead of urethane adhesive meets one of the following conditions:

    • Intact without portions of the bead missing
    • Solidly adhered to the pinchweld flange and no corrosion is present on the flange
    • Uniform in shape. Smooth, without multiple cuts or loose material present

Also use the short method under the following conditions:

    • When repainting of the opening or collision repair/sheet metal replacement is not required
    • When urethane adhesive deterioration is not evident (no powdery residue)
