My radiator man has told me there are two different types of rust inhibitor. One type will settle to the bottom of the cooling system if a car is laid up for the winter. The other type stays in suspension. I use the latter type but I cannot quote the brand name as I am not at home where my rust inhibitor is kept, but for a car used year round either type is OK.
