Worked for me

Good service.

Made payment and got a call from head office as product was dispatched. Arrived two days later (express delivery)

Had a blown head gasket coolant leak. White exhaust fumes and water droplets from exhaust.

Within 3 days there was a drastic improvement and no more white smoke and droplets from exhaust.

Will work if leak is small enough. Worth a try. Worked for me.
