Review: 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.

## Questions & Answers

**Q: Does it stop leaks from top of Raidator**
A: If you are asking about a plastic top tank that is clamped to an aluminum radiator the answer is "maybe"I had three vehicles with very tiny radiator leaks. All from the clamp seam at the sides (these were all Honda radiators) and the stop leak did work on those. One car required three bottles. But an older car with an all brass tank could not be leak stopped with just the stop leak. It did allow the owner to continue to drive the vehicle until he arranged for a real repair. The top and bottom brass tanks were unsoldered from the destroyed core and a new core was soldered in. Creating a brand new radiator. This was in an old 1060's Chrysler.

**Q: Will this product seal leak from water pump gasket**
A: We would recommend our Radiator Stop Leak Tablets for that issue P/N HDC.
