I was told the product is only effective during the first heat cycle. That may or may not be true and I am leaning towards it probably is At any rate, I did not get a great deal of confidence on the technical part of the conversation but if you are concerned if they will provide money back I believe they will. I did a lot of reading on this product before deciding to try it and I am glad I did, it provided a lot of reference to consider. I will describe my situation in case it provides insight to anyone considering this product.
I have had symptoms of a blown head gasket in a 2004 4Runner V6 for a long time. My symptoms were the coolant reservoir becoming over filled. When the vehicle was hot and running you could see air bubbles coming out of the overflow reservoir hose into the reservoir coolant. Occasionally, I would get check engine light for misfire on cylinder 6 (and more recently cylinder 2 as well) at startup but it would clear itself in short order. Lately, the vehicle had been starting rough, especially after a long drive and cool down. Presumably the rough start was due to the lack of combustion in the cylinder due to water that drained into it and/or lack of compression due to leaky head gasket that vastly improved when the engine began to heat up and expand. I never had any white steam coming from the tail pipe other than the standard moisture burn off in the exhaust system that any vehicle will exhibit on cold startup especially on cold days. I have not had any water in the oil.
There are specific additional instructions to follow if you have back pressure in the cooling system like I did. The treatment calls for removal of spark plug of the suspect cylinder and then run up to temp and for an additional 30 minutes at high idle. I did not compression test my cylinders and frankly all three spark plugs on bank 2 of my engine looked pretty suspect for water intrusion. Given this, I was not too confident but I know cyl 6 was the initial issue and likely the worst so I pulled it and left the radiator cap off and ran the treatment. I then let the car cool down, replaced the spark plug and let the car sit over night. The next morning I fired it up and still had bubbles coming into reservoir. I then went for a drive on the highway for about 8 miles. Back at home still bubbles. I figured the treatment did not succeed. I figured my engine was no better or worse off after the treatment. Fast forward almost two weeks and I have had no rough starts and the radiator is staying completely full, reservoir is maintaining a stable level once cooled down (normal) and I am not seeing bubbles in the reservoir any longer. I think it worked!!! I am thinking the bubbles I saw the first couple of days may have been the system purging air as would be normal after any coolant change. OR the product continued to work over a few heat cycles to ultimately cure my issue.
The weather has been cool since I did this treatment so the cooling system is definitely not being taxed heavily. I will try to remember to update this in a few months once the weather is hot to confirm if it is still holding up.
head gasket becomes a hard resin filler. I have herd people going 50 to 100,000 more miles from using this stuff After using it i change out my plugs ,oil, and replace the water, with radiator fluid your good to go. This stuff saved me a bundle . yes this tuff works Jim

I put two bottles in the radiator followed the instructions I drove up the highway for about 20 minutes then let it sit overnight .
The next morning I topped the radiator up and went for a spin and it didn't use any water .
That was six weeks ago and its still fine.
