It Work For Other Than Radiators
We have a waterfall made out of lava rock. Lava rock can be quite porous. The water reservoir is in the bottom of a large lava rock. Tarred the inside as best could to reduce leakage. Still leaked notably. Decided to try Bar's Leak. Very pleased with the results. The leakage greatly reduced. Likely most of the reduction in water quantity is due to evaporation.

Stubborn leak fixed.
I usually don't put much stock into stop leaks. If you're using one then you already have a problem. Well the thing is, I replaced my radiator where the leak was. Problem solved. Now I have a leak from the lower radiator hose to the motor. I couldn't find the "sweet spot" for the clamp and it just kept leaking. No matter where I put it. One would think that it's leaking from the water pump. Pump is fine, got a leak around the hose. Moved clamp up, leaked less, move clamp over to the flange, leaked more. Within six minutes of using this my leak is gone. If you have a small leak that's driving you up the wall. This'll fix it.

Yes
The stuff works. I put it in a 2006 Chrysler Town & Country with over 260,000 miles, haven’t had a problem since I put it in, highly recommend it.

Leak stopped 100% immediately
I was skeptical that this would work on my Porsche Boxster and that it would not cause other problems. I had an annoying drip from the pressurized coolant reservoir, which was new. I didn't want to make another trip to the shop. Every day there would be a small puddle under the car and I had to top off the coolant every 2-3 weeks. The next day after the treatment, no puddle. I've had to top off once in the last 6 months.
