Saw a huge difference in surface finish after switching coolant brands

I was getting these weird streaks on aluminum parts for like 2 months straight at my shop in Tulsa. Finally swapped from the generic stuff to Blaser Swisslube and the finish cleaned up right away. Has anyone else seen that big a change just from changing coolant? I'm wondering if it was the concentration or the actual formula.

Wait, Blaser actually fixed it that fast?

Three weeks turnaround on mine with the same issue. You just gotta email support with the serial number and the receipt, otherwise they drag their feet. They ship the replacement bolt assembly direct to your door, no FFL needed.

Right? Same here, I had to wait almost a month for my Ruger to come back from the custom shop once. @anderson.piper mentioned the serial number trick, but I swear I sent mine in with a handwritten note and they still lost it for two weeks before finally shipping it back.
