RisloneHEAVY DUTY BLOWN HEAD GASKET REPAIR

The best head seal product I've used.

Killed my engine who knows what it blocked -took thermostat out to let it circulate then put new one in -no real change after adding and then overheated and wiped out a cylinder -subjective as to if this would happen as put it in to stop a leak but was running fine bar coolant loss before -no return or money back like some other headline product and an expensive item for sodium silicate with metal suspension --hopeful you have better luck

Waste of money . Total rubbish
