Aftermarket-- typically more affordable, may utilize lower‑grade rubber; confirm fitment and product specs.For the majority of applications, an OEM‑quality EPDM gasket uses the finest balance of toughness 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 needed), isopropyl alcohol, tidy ragsSecurity GearGloves, shatterproof glassOptionalPainters tape (to safeguard surrounding paint), heat weapon (for softening old adhesive)Tip: Use a plastic trim tool instead of a metal screwdriver to prevent scratching the window or paint.5.

Protect any clips or fasteners that hold the gasket to the window glass or body. Reinstall the trim panels in the reverse order of removal.5.5 Final ChecksReconnect the battery and check the window operation (open/close, seal integrity). Inspect for leaks by running water over the window with a garden hose while observing the interior. Re‑torque any bolts to the manufacturer's specifications (typically 8‑12 Nm for the majority of sunroof assemblies).6.
