Aftermarket-- typically less expensive, may use lower‑grade rubber; confirm fitment and material specifications.For many applications, an OEM‑quality EPDM gasket offers the very best balance of sturdiness and expense.4. Tools and Materials NeededClassificationItemsHand ToolsFlat‑head screwdriver, plastic trim panel tool, socket set (metric), torque wrenchConsumablesGasket replacement (pre‑cut or bulk roll), gasket adhesive (if required), isopropyl alcohol, clean ragsSafety GearGloves, shatterproof glassOptionalPainters tape (to secure surrounding paint), heat gun (for softening old adhesive)Tip: Use a plastic trim tool rather than a metal screwdriver to avoid scratching the window or paint.5.

Check the frame for rust or damage; file or sand any sharp edges that might puncture the brand-new gasket.5.4 Installing the New GasketDry‑fit the new gasket to verify alignment. Numerous gaskets are supplied with pre‑applied adhesive support; if not, use a thin bead of gasket adhesive along the frame.

Secure any clips or fasteners that hold the gasket to the window glass or body. Re-install the trim panels in the reverse order of removal.5.5 Final ChecksReconnect the battery and check the window operation (open/close, seal stability). Examine for leakages by running water over the window with a garden tube while observing the interior. Re‑torque any bolts to the maker's specs (generally 8‑12 Nm for most sunroof assemblies).6.
