It's a fairly regular discussion topic Jon. Anti-freeze is not the way to go if cooling is marginal, as it makes your engine run hotter. Some advocate Fernox as an inhibitor. I'm currently trying out Penrite's classic car coolant, which is doubtless much the same thing, but claims to be formulated for cars.
