Permatex Form-A-Gasket #2 Sealant 11 oz — Non-Hardening, Oil-Resistant Gasket Dressing

Permatex Form-A-Gasket #2 is a slow-drying, non-hardening sealant that seals cut and stamped gaskets while allowing easy disassembly when needed.

When a preformed chemical gasket isn’t practical, technicians and DIYers need a reliable product that fills gaps, resists oils and fuels, and won’t cure into a rigid bond. Permatex 80011 Form-A-Gasket #2 is formulated to dress flexible and stamped gaskets, providing a durable fluid barrier from -65°F to 400°F (-54°C to 204°C) without permanently locking parts together. Its aviation-approved chemistry and compatibility with common shop fluids make it a versatile option across automotive and light aircraft maintenance.

How does this sealant perform on cut or stamped gaskets?

Form-A-Gasket #2 is engineered to tack and seal edges of flexible and stamped gaskets, preventing fluid seepage while preserving the gasket’s ability to be removed later. It remains pliable rather than curing hard, so it fills surface irregularities without creating a brittle joint.

• Adheres to rubber, cork, and many composite gasket materials.
• Fills small voids and surface imperfections for a consistent seal.
• Stays flexible to allow future disassembly and service.

Will it resist gasoline, oil, and other shop fluids?

Yes — Form-A-Gasket #2 is formulated to withstand common automotive fluids, making it suitable for engine compartments and oil-retaining assemblies. Its resistance reduces the risk of softening or displacement when exposed to fuel, oil, or grease in normal operating conditions.

• Resistant to gasoline, engine oil, and lubricants found in workshops.
• Stable across a broad automotive temperature range: -65°F to 400°F.
• Suitable for areas where fluid exposure is expected, like valve covers and oil pans.

How easy is it to apply and remove during maintenance?

Application is straightforward: apply a thin, even bead to the gasket or mating surface and assemble per manufacturer recommendations. Because it does not harden into a rigid gasket, components can be separated for inspection or repair without chipping or scraping away cured material.

• Slow-drying formula allows adjustment before setting.
• Non-hardening texture simplifies later disassembly and cleaning.
• Works well when you need sealing priority over permanent bonding.

Which parts and projects is this sealant best suited for?

Permatex recommends this product for applications where a soft, conforming seal is needed rather than an adhesive bond. Typical uses include valve cover and oil pan gaskets, plus any stamped or flexible gasket joints that require a fluid-tight seal without permanent fixation.

• Valve cover gasket dressing and sealing.
• Oil pan gasket edges and repair of cut gaskets.
• Flexible or stamped gaskets on both import and domestic vehicles, and aviation-approved tasks.

Who is this for: Permatex Form-A-Gasket #2 is aimed at professional mechanics, aircraft maintainers, and home mechanics who need a dependable, non-hardening gasket sealant. If your priority is a reliable fluid barrier that permits later disassembly — especially on valve covers, oil pans, or cut gaskets — this product offers the temperature tolerance, fluid resistance, and pliability required for routine maintenance and repairs.
