Had a small radiator leak, and even after several months the reservoir level hasn't moved an inch.
Good stuff!

Makes your coolant look like mud, but I use it for all older cars I do cooling system work on. This is great in my opinion for preventative maintenance, especially on abused systems that may have rust, as it contains oil.
I put it in an old S-10 after replacing the head gaskets because the block had developed some rust because of using water to limp it along and then taking a couple weeks to finish the process. I've had no overheating problems since. I noticed a slight drip from the radiator when idling a couple days later. Months later, I still haven't had to add water or replace the radiator. I wouldn't count on it to fix a head gasket, but I strongly recommend it for use for small leaks and as a preventative measure.

Better than major repairs.

best to seal leaks. Gaskets are very hard to reach - this made it much easier to stop. It's been a couple of months and no drips.
