I agree that it may be a band-aid approach to the inevitable. I couldn't figure out where my leak was coming from and it was very small. I saw no drop in the coolant level reservoir, just noticed an accumulation of dried coolant and one drop a night on the ground.
For me, I used BARS stop leak and its still working 8 months later.
I wasn't convinced it was my head gasket and my leak was very minor, so the 'quick fix' did the trick. I did notice it made the coolant tank darker though...
I plan on flushing the system this spring.
