Does the BMW X5 hood need sealant after replacement?
1 Answers
After replacing the BMW X5 hood, applying sealant is not necessary and not highly recommended. Requirements: Certain areas of the hood experience relatively higher temperatures due to engine heat. Original equipment manufacturer (OEM) parts undergo safety and durability testing, with the hood slope, angle, and installation tolerances all engineered to specific standards. Disadvantages: Installing sealing strips has a significant drawback: from a distance, all gaps appear as black lines, which is aesthetically unpleasing. Additionally, during car washes, the sealing strips are prone to falling off once they get wet, losing all adhesive properties. Although some manufacturers provide adhesion promoters, they are generally ineffective.
