⚫Weatherstrip Conditioner

Weatherstrip conditioner keeps the rubber door, trunk, and window seals soft so they don't crack, squeak, or freeze to the body in winter. Wipe it on twice a year — silicone or glycerin-based, never petroleum (petroleum degrades rubber over time). The five-minute job that prevents a $400 weatherstrip replacement when a seal finally tears. Especially worth it on convertibles, sunroof gaskets, and any car that lives outside. A microfiber applicator and clean towel are all you need.
