Review: Does the job perfectly! - Makes life so much easier with this. I used it to cover the clutch cover on a Bonneville T100 after replacing the clutch springs. Creates a nice seal with no oil leaks. Make sure both surfaces are free from old gaskets and debris.

## Questions & Answers

**Q: would it work on a cylinder head? much as used for racing?**
A: There is no single answer.  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

Cracking stuff - wouldn’t use anything else!

### ⭐⭐⭐⭐⭐ Copper thermal spray gasket
*by M***E on 5 September 2025*

I used it on a three layer used metal head gasket as I needed to finish up quickly. A brand new head gasket was not only expensive but was not available in the time I needed to finish the rebuild. It worked fantastically and is still holding tight with no issues.
