As Intended, Awesome Product
This product is a powder version of the pellets sold under Bar's Leak and AC Delco brands, and I have sold and used these for decades in the auto repair industry in customers' cars for cooling system conditioning after system repairs and/or maintenance. It is a gentle product that does not clog heater cores and tiny passages, with outstanding lubricating properties and decent sealing.It has always been marketed as being a factory, OE product that many automakers use in new cars on the assembly line before they're delivered to dealerships.Yes, this will seal small leaks and seepage areas pretty well, but it is best used as intended: as a sealing AID after engine or cooling system reassembly, and as a maintenance agent with cooling system service. Adhere to a sensible maintenance schedule and use this product anytime coolant is drained and refilled and you will never have use for a sealer of any kind.I just checked my database out of curiosity, and found my little three-bay shop has sold 119 in the past two years. I've been selling this for 25-plus years though, so it might be thousands.And my customers never have coolant leaks.Fair enough?

AN AMAZING PRODUCT
THE PRODUCT SEEMS TO WORK FINE. MY PRIMARY PROBLEM WAS ' OVERHEATING ' CAUSED BY A SLIGHT CRACK IN THE PLASTIC PORTION OF THE RADIATOR HOSE OF A 1995 BMW. AT THE MOMENT THERE IS NO OVERHEATING.SO FAR I HAVE NOT TAKEN THE CAR ON A LONG RUN AS OF YET.MY CONFIDENCE IS ' UPBEAT 'AND I CAN HONESTLY RECOMMEND IT TO OTHERS .WALTER BROWN

worked great!
I tried everything on my 99 keep to get the radiator plug so stop leaking. I was worried to tighten it further since the core is aluminum. But after 2 days with this, the leak is fixed.

works great
I had recommened this product by a professional mechanic. I have used this product for over twenty years and it worked every time. This is lowest priced radiator sealer and it is very easy to store in your car for emergencies.
