Disappointing

About Me Advanced

Pros

    Cons

    • Ineffective

    Best Uses

      Today, it was sunny and maybe around 20 degrees outside in Bristol, RI. I keep several gallons of the -50 degree antifreeze on my boat. This afternoon, I opened one of the containers and noticed about 1/4 of the antifreeze was frozen to a hard slush. I have a hard time believing this product would not be frozen solid at the rated temperature.
