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.

Copper thermal spray gasket
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.

Essential when using a solid copper head gasket.

Cuando se trata de potenciar extremadamente un coche cada detalle cuenta, y este es un detalle mas que sin duda ayuda a mantener la fiabilidad del motor en preparaciones fuertes. En mi caso lo he usado para: Clio 1.2 16v tce, potencia de origen 100cv, potencia actual 170cv Toledo 1.9TDI, potencia de origen 110cv, potencia actual 200cv Y de momento no tengo problemas de fiabilidad con ninguno.
