FACTORY GM ASTROROOF Reproduction SEAL FOR THE GLASS
This is a reproduction of the actual glass seal.
First, you need to be sure your car has a factory GM astroroof, sometimes referred to as a “sun roof.” The factory astroroof will have the code “CF5″ on the trunk ID label. If it does not have this code, you probably have an aftermarket astroroof and this seal will NOT fit.
This seal is “MADE IN THE USA ” and are superior to what GM had made originally. It has a firm compound with a smooth outer jacket that is cast into the coating. It is not wrapped like GM, which is why the GM seals wrinkle. This allows the glass to ride on a smooth surface. This gains better glass coverage, which means better sealing and less resistance on a 25+-year-old motor.
NOTE - We recommend the installation be done by a qualified shop.
One helpful tip is to take an air hose and make sure all the drain holes are clear of debris. These drain holes are located on the corners which are visible when the glass is in the open position. If the drain holes become clogged, water can back up and ruin the surrounding headliner.
NOTE - Once compressed, this new reproduction seal is exactly the same as the original. For best results, wax it and put the window in the closed position for at least 48 hours (with all the windows in the up position.) This should be done in a warm/hot environment.
Another nice finishing touch for any exterior restoration.
