Not suitable for cylinder head gaskets or for parts permanently exposed to fuel. This product should not be used to replace composite head gaskets, specifically where tolerances are predetermined and are critical to engine performance.Not suitable for some metals such as galvanised iron, lead, mild steel, brass, copper, zinc or tin as it may cause corrosion. This product releases acetic acid during the curing process, therefore it's not suitable to use on alkaline surfaces such as fibrous cement, concrete, asbestos, plaster or to come in contact with the following surfaces like marble, granite or any other natural stone as it may cause discolouration on the surfaces. It should also not be used at the back of mirrors as it will de-silver the mirror-backing.
