Yes I know I am going to have 20 people tell me to used distilled water, I know I know I know. My question is not whether I should use it, but which is the safest and most recommended, basically which coolant has had the least amount of problems with the die separating from the water/coolant. I am afraid of premochill's dye, I want a blood red color and they have it but I have heard to many bad stories about them is there something else? Blood red? Not bright red, pink, or anything like that, looks ugly.
