Weatherstrip Lubrication
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Silicone grease on weatherstrips will make them last longer, seal better and not stick or squeal. Apply silicone grease with a clean cloth. During very cold, damp weather, more frequent application may be required. Refer to Fluid and Lubricant Recommendations .
