Put some product similar to chemi weld in the GTR - the thermostat coughed open, blew pressure into the radiator - the recoverable cap let the fluid into the storage tank - then it spashed all over the engine bay.
it was a little bottle with what looked like a clear liquid and then what looked like a rust emlusion at the bottom - you shake the bottle and pour into the radiator - but it's not chemi weld - I just cannot remember the name.
It's ;left what looks like a white scale or calcification that has attached itself to everthing and anything under the bonnet and engine bay - to which I'm massively Pissssed to say the least.
tried mineral turps - wax and grease remover
any suggestions on cleaning will be appreciated
