Permatex Silicone Spray Lubricant
Automotive-grade smooth. Safe on everything.
by Permatex
Permatex Silicone is the automotive industry's go-to for weather stripping, hinges, and anything rubber or plastic that needs to move freely. Won't swell rubber. Won't stain surfaces. Just pure, friction-free performance.
Permatex carved out its niche by focusing on what it does best: keeping automotive rubber soft, pliant, and responsive. The formula conditions weather stripping while depositing a protective silicone barrier that prevents moisture from freezing between the seal and the body panel. It's a remarkably specific product that outperforms general-purpose silicones in its narrow domain — if your primary concern is maintaining the integrity and performance of rubber seals and gaskets, this specialist will leave you more satisfied than any jack-of-all-trades alternative.
What We Like
- + Purpose-built for weather stripping — knows exactly how to handle rubber
- + Restores dried-out seals to supple, flexible condition
- + Budget pricing lets you lubricate every opening in your vehicle
- + Prevents door gaskets from freezing shut in winter — no more stuck entries
What Could Be Better
- − Smaller 10.25 oz can feels inadequate for larger jobs
- − Automotive focus means it's not the best multitasker in the workshop
- − Doesn't penetrate as deeply as dedicated penetrating oils on corroded fasteners
Who Should Buy This
Car owners tired of groaning doors and sticky trunk seals. Essential for anyone in cold climates where rubber gaskets freeze, bond, and refuse to open without a fight.
