How to Repair a Window Channel on a Car

The window channel on a car is where the water runs down and away from the glass. Window channels also help keep water out of the inside of the car. However, the seams in window channels may eventually separate due to the sheet metal flexing. When this happens, reseal the seams in the window channel.

Instructions

1

Clean the window channel with soap and water.

2

Dry the channel with a lint-free towel.

3

Apply a bead of seam sealer to the seams on the window channel. Make sure that you get good coverage on any seams that are showing visible cracks.

4

Smooth the sealer across the seams with your fingers.

5

Allow the seam sealer to dry for at least 24 hours before exposing it to water.
