Coolant sealers

Anyone had any experience with Motor Purr Seal Up. I have a bottle sitting on a garage shelf for about 15 years now and don't remember anything about it. Is it a good product or not.

found this on google.

tried a similar product called motor purr seal up. It works on the same principle as the Car Go Seal up but it does not contain the liquid glass. Luckily, I was not having an overheating problem, just the constant coolant loss and the large plume of white smoke from the exhaust. The motor purr seal up can be added through the top radiator hose(since we don't have radiator caps) without having to remove the coolant. It also works with any color anti-freeze. I poured it into the top hose and ran the car for about two hours with the heater blower on high. Boy, did it get warm inside the passenger compartment. (no, I wasn't sitting inside the entire time...hahaha) The directions on the bottle only required 30 minutes of circulation through the system, but I ran it for the two hours just two be on the safe side. It ran in front of the house for about an hour, and after that I took it on the highway, driving at a normal speed, no rapid accelerations to put any undue pressure on the head gasket. When I returned home, I topped off the reservoir with fresh coolant and let it rest for about six hours. I came out about 4'Oclock in the morning and started it up and let it run for another hour with the heater blower on high. I DOUBLE CHECKED that the coolant return line from the radiator to the reservoir was flowing an unrestricted. No problems. I had very good coolant flow. I backed the car up to check for coolant leaks on the ground...NADA!! It's been two and a half weeks and no loss of coolant, no leaks on the ground and the compression in the engine during acceleration is even much better than before. This product was guaranteed a permanent fix by the manufacturer. I have not seen any adverse effects whatsoever, and I must say that I am very satisfied so far with the results. A small bottle of the motor purr seal up was $7.99 at Meyers Import Auto Parts here in Vegas. I'm sure that some other parts stores must carry it on the shelf. I just felt better knowing that I didn't have to worry about my cooling system being completely sealed up should a small quantity of antifreeze be present in the system.

Thanks for the research Bill, I suspect it's a good product. Looks like it has copper powder mixed in it.
