What is the purpose of windshield sealant and weatherstripping?

• A. Sealant prevents water intrusion and seals gaps; weatherstripping provides a proper fit and reduces wind noise and air leaks.
• B. Sealant improves UV resistance.
• C. Weatherstripping is decorative.
• D. Sealant is used to color-match.

Answer: (A)

The main idea is that these components are about sealing and getting a proper fit to keep the interior dry and quiet. Windshield sealant fills the gap between the glass edge and the body, creating a watertight and airtight bond as it cures. Weatherstripping provides the compression and seal along the window opening, giving a snug fit that reduces wind noise and drafts and helps prevent leaks. Together, they ensure the glass stays in place and that water intrusion and air leaks are minimized.

The other ideas don’t fit because UV resistance isn’t the primary job of sealant, weatherstripping isn’t used for decoration, and sealant isn’t chosen for color matching.
