well, i'm asking cause I cant use water wetter or antifreeze in this application. its not for a computer water cooling system. its actually for my job attempting to design a new thermal diving suit for the navy. we're using a liquid heated/cooled inner garment to suppliment the insulation, but have many dissimmilar metals in our testing and control apparatus currently. our stupid "stainless" steel flowmeters are corroding left and right, but as per the manufacturers specs of those flowmeters, we cant put water wetter, or antifreeze through it, but we can put straight glycol through it. oh well, we'll see what happens, time to go looking for corrosion inhibition alternatives.
