Permatex Copper Spray-A-Gasket Hi-Temp Adhesive Sealant is a fast-drying, metallic copper sealant that helps dissipate heat, prevents gasket burnout and improves heat transfer. It seals instantly and fills minor surface irregularities and hot spots. Resists all types of automotive fluids, especially gasoline, and has a temperature range of -50 degrees Fahrenheit to 500 degrees Fahrenheit. Suggested applications include cylinder head gaskets, carburetor gaskets, exhaust manifold gaskets and other high temperature applications. When a chemical gasket is not an option, Permatex offers a wide range of gasket sealants suitable for applications on both import and domestic vehicles of any model year or performance caliber.
The adhesive works well, but the aerosol can was a bit tricky to use. I had to shake it a lot for consistent spray. I’m satisfied with the sealing quality, but the application could be smoother.

Great for high-temp applications!
I used this Permatex copper spray gasket on my car's exhaust system and it worked like a charm. The high-temp adhesive held up perfectly even during intense heat, and it was easy to apply. The 12-pack is a steal for the price!

Good product for the price!
I bought this pack of 12 for my garage and I’m impressed. The copper spray goes on evenly and creates a reliable seal. I've used it for both automotive and home projects with great results.

Must-have for DIY mechanics!
This copper spray gasket is now my go-to for sealing gaskets on my bike repairs. The 9 oz size is just right for most jobs and the pack of 12 means I won’t run out anytime soon!

Not what I expected
I was hoping for a stronger hold. After a couple of weeks, I noticed leaks in the gasket I applied this to. It may work for other applications, but it didn't hold up for my needs. Disappointed.
