If the car is still new, go with the best, or honda products... but if its more then 5 years old.... dont bother...
It does not cause your radiator to rust or corrode. It causes particulates to precipitate in the coolant once you go through a few heating and cooling cycles in combination with exposure to the materials used to build the engine. The solids in the coolant will then wear down the water pump.
