The use of this sealant depends on the type of gasket you are working with. If you have solid copper gasket or a metal clad composite (say... copper foil skin sandwiching a fiber core) then yes it would work on those gaskets. If you have a composite fiber gasket with fire rings and no coating then again... it would work. If your gasket is of fiber construction and has a shiny coating on it that looks like varnish... don't use this spray without referring to the literature supplied with the gasket. Many modern gaskets come with a pre-applied sealant coating so you don't want to add additional (and possibly incompatible) sealant spray. Sorry, but as I said, it really depends on the type of gasket you are working with. **Q: will this coating make the head harder to remove if necessary?** A: Actually, I used it and had to remove my head gasket six months after, not because of this stuff though. The gasket came off no problem. I don’t know if this stuff really does anything though. As long as your head and block are surfaced properly, you shouldn’t need it. **Q: Can this be used on felpro gaskets for timing covers, thermostats, water pumps and so on?** A: I used it on head Gaskets and worked well so I don't see why not its a really tacky solution help hold gasket in place and seal **Q: Can this be used on a gasket that sits between an aluminum head and aluminum engine block? Possible corrosion?** A: We use this on aluminum heads and blocks all the time for Mercedes-Benz ## Frequently Bought Together - Permatex 80697 Copper Spray-A-Gasket Hi-Temp Adhesive Sealant, 9 oz. net Aerosol Can , Orange - Permatex 85080 Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker, Sensor Safe And Non-Corrosive, For High Flex And Oil Resistant Applications 9.5 oz - Permatex 81950 Ultra Slick Engine Assembly Lube, 4 oz. , Red --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/3212940-permatex-80697-copper-spray-a-gasket-sealant](https://www.desertcart.vn/products/3212940-permatex-80697-copper-spray-a-gasket-sealant) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-10-18*
