How to Install Quarter Glass Vertical Seals

To properly seal your car, you need quality parts, like we sell at SuperCar Specialty, and a correct installation. Time spent carefully following these instructions will help you achieve the "like new" results you're after!

General Hints:
1. Take your time! Hurrying, especially when working with adhesives, can cause you to damage your seals. Regarding adhesives, we recommend either Permatex or 3M Black Super Weathersrip Adhesive. They are body oem strength, and the black color is much more forgiving if you happen to get any of it on you or your car.

2. Check your packaging and invoice to confirm that the seals you are about to install are for your year, make, and model car.

3. Don't remove both seals at once. Remove and replace 1 side at a time, starting with the passenger side which is the least often used.

4. Do your quarter glass and door glass line up correctly? If your door and/or rear quarter glasses need adjustment, the new quarter glass seals may not seal properly, or could be damaged by the mis-alignment. A little time spent on correcting alignment problems can make your seals last much longer.

A) Preparation:
Clean out any rust or debris with a small wire brush being careful not to scratch the chrome. You can put a strip of masking tape on the edge of the chrome edge molding before you start, to protect it. Remove any old adhesive, using a release agent. Wipe the surface with a clean cloth. Clean the entire inner channel on the chrome edge molding, removing any debris present.

B) Remove Old Quarter Seals:
Remove your old seals in one piece if possible, using care not to pull off the chrome edge molding on the front edge of the quarter glass. You may have to remove your u-shaped door jamb seals to get at the quarter glass seals. Remove any screws at the base of the old seal. Grab the old seal and firmly pull down. Pull the old seal DOWN out the the chrome channel. Do not pull outward, which can loosen the edge chrome. If your old seals will not come out easily, squirt WD40 or other light penetrating oil into the chrome edge molding groove and try again. If that does not work, try attaching vise-grips or pliers to the edge of the old seal and then gently tap downward on the vise-grips with a hammer until the seal comes free.


C) Apply Lubricant: Apply a light lubricant or soapy water to the back of your new seal. If your model car did not have screws attaching the quarter seal, you will have to apply a small bead of adhesive to the inside of the channel. (Figure 10A).

D) Slide New Seal On:
Slide the new quarter window seal into the chrome edge molding starting at the bottom. Replace the screws at the bottom of the base if necessary (Figure 10B) and reattach the u-shaped door jamb seal.

E) Afterwards:
Check the alignment of your door and rear quarter glass to assure that there is no interference.
