3.2 OEM vs. Aftermarket

OEM (Original Equipment Manufacturer)-- exact fit, generally EPDM, backed by the lorry warranty.
Aftermarket-- frequently less expensive, may utilize lower‑grade rubber; verify fitment and material specifications.

For the majority of applications, an OEM‑quality EPDM gasket provides the finest balance of durability and cost.

Tip: Use a plastic trim tool rather than a metal screwdriver to avoid scratching the window or paint.

5. Step‑by‑Step Replacement Procedure

5.1 Preparation

Park the car on a level surface area and engage the parking brake.

5.3 Cleaning the Surface

Wipe the breeding surfaces with isopropyl alcohol to eliminate residual adhesive, dirt, and oil.
Check the frame for deterioration or damage; file or sand any sharp edges that could puncture the brand-new gasket.

Reconnect the battery and check the window operation (open/close, seal stability).
Inspect for leakages by running water over the window with a garden hose while observing the interior.
Re‑torque any bolts to the producer's specifications (generally 8‑12 Nm for many sunroof assemblies).
