It is MAGIC for sure!!!

It works. My car was overheating and losing all its water. A compression test also confirmed carbon monoxide in the cooling system which means an expensive cylinder head repair job was due. I decided to rather try Gasket Magic before spending thousands. My car has been pushed very hard since, I've used this product and everything is still fine. In fact, it's better than fine! The day after using the product, the idle was so quiet that I panicked and thought the car is going to stall, but it's actually returned to the silent idle of a healthy engine because everything is 100% sealed up. It's even more nippy as well. Do yourself a favour and use this product before a gasket repair. Oh, just a tip. The manufacturer recommends using half-a-bottle on 4-cylinder engines and idling the car for 10min. I used the whole bottle on my 4-cylinder and idled for 40min. I don't do things half-baked and it seems that applying the product in my way sorted out the issue, properly.
