Last year I didn’t know any better and my windshield whisper fluid froze and the tank detached from the line. I had no whisper fluid until I got the car into a mechanic. I personally bought my -30 F fluid at a Home Depot but I imagine you can get it anywhere that has car stuff.
Edit: Fuck. I need an editor.

I wish the trucks hammering their air brakes as they drive by my house were using whisper fluid. Quiet that shit right down.
