Heads up on that new coolant concentrate from Acme Supply

Switched to it three weeks ago because the price was good. By yesterday, I had rust spotting on three different fixtures that never had issues before. Anyone else run into this with their brand?

Yeah, my coolant mix looked like a science project too, but I'm the one who always fails the class. I had the same rust issue, which is a real bummer because I was pretty proud of myself for finding a deal for once. Now I'm back to the old brand, feeling like I paid for a lesson instead of coolant.

Rust spotting could be from a bunch of things though, not just the new coolant. I've been using that Acme concentrate for a month now with zero problems.

My last coolant mix looked like a science project gone wrong.
