Exterior weatherstrips are exposed to a variety of environmental elements, including UV rays, acid rain, insect and bird residue and atmospheric

fallout. All of these may effect the appearance of the weatherstrips; however, they do not effect the functionality of the weatherstrip.

Weatherstrips that are discolored should not be replaced under the normal GM New Vehicle Warranty.

Weatherstrip Maintenance Instructions

Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Clean the weatherstrips with a mild soap and water

solution. Apply silicone grease with a clean cloth. During very cold, damp weather, frequent application may be required. Refer to the information

below for the recommended maintenance products. Weatherstrips that are not maintained may crack and weather due to environmental elements.
