So what do you guys think of this stuff? Never tried it, but I was thinking I'd give it a shot if there's something to it. Went to an auto parts store, all they had was something from Pro Blend (?). Bottle said to drain rad, add this stuff and water. No coolant but what was held in the block! I don't like the sound of that. Got rresh coolant now, if there's a good additive that can just go in, I'll try it. Is there a good brand, and does it really seem to do some good?
