How do you replace the roof moulding on a jaguar 2003 x type?

To replace the roof moulding on a 2003 Jaguar X-Type, first, carefully remove the old moulding by gently prying it away from the roof using a plastic trim tool to avoid damage. Clean the surface where the new moulding will be applied. Next, cut the new moulding to the appropriate length, ensuring it fits snugly, and press it into place, securing it with adhesive if necessary. Finally, check for a proper seal and ensure there are no gaps.
