Use 3M™ Silicone Paste for the many areas of your vehicle that require long-term protection from the harsh conditions of environmental exposure. This non-hardening, water-resistant paste can be applied heavily to help seal out contaminants and weather. It can also be spread thin for nearly invisible lubrication and protection.
So many uses, so much value — our 3M™ Silicone Paste is a non-hardening, water resistant, 100% silicone-based compound designed to lubricate and protect a broad range of surfaces and surface combinations. This compound is suitable and safe for use on the plastic-to-plastic, plastic-to-metal, plastic-to-rubber, rubber-to-rubber, and rubber-to-metal areas throughout your vehicle. It both conditions the rubber to keep it soft and supple and protects it from damage due to wear & tear and environmental exposure. It has excellent dielectric properties, meaning it insulates rather than conducts — use it under your hood to protect battery terminals, ignition systems and other low voltage electrical parts where arcing can cause oxidation or corrosion.
