water leak at headers

dump it all in. I had a radiator that had a pinhole in the front from a rock. It was pissing onto the crosswalk at a light right out the grill. I pulled into Trak auto and dropped 2.99 for a tube of this stuff. Let it cool over a burger and dumped it in and topped off. It was still leaking but it got slower and slower and finally stopped, leaving a trail of glitter down the radiator. I like the oily looking stuff with the little black balls in it. Doesnt leave compacted glitter in the block. But it does work.
