I have been reading on the Hammerite website and they say the Hammerite paint is petrol and acid resistant when fully cured and is ok up to 150 degree centigrade or 300 degrees fahrenheit so I am going to try that. I don't think the engine case gets up to those temperatures as the thermostat keeps it around 88 degrees centigrade/190 Fahrenheit.
