I would definitely add the caveat of "your mileage may vary" to that. A
relatively clear radiator and heater cores won't be bothered (much) by a
little Barr's, but I've seen cruddy but serviceable radiators stopped right
up by the stuff, solving a minor leak only to create a chronic overheating
situation. 'Course if you're just looking for band aid solutions, that's
definitely one of 'em.
