I bought this product a week before…
I bought this product a week before Christmas because my car started pressurizing coolant into the overflow bottle and getting hot due to low coolant in the radiator. I never let it boil and had to nurse the car home. I read all the instruction on how to applicate and did this as per manufacturer instructions and let the car idle for about 45min. I took the car for a short drive and found that it is still pressurizing into the overflow bottle . I returned home and let it sit and cool back down overnight and tried it again the next day. You can see the coper particles in both the radiator and overflow bottle but it obviously didn't fix. I was hoping to get through Christmas and the New Year before I may need to have the head gasket replaced. Sorry guys this didn't work for me. Joe2

Hi Joe,
This is a fair review score, given that we have been unsuccessful, especially if you have followed the specific over-pressurising instructions.
As you know, if the symptom is severe, backpressure rather than a coolant leak into the cylinders, we will struggle to make the repair.
It was always worth a try, but given the details you have provided, it was a best-efforts-only attempt.
