I didnt read any of this topic, but wouldn't Zerex G-05 work as an anti corrosive?
According to Valvoline and some thing I saw on TV on TLC they use it on high performance cars because of the fact it transfers heat so well, lubricates any sealings, and stops corrosion.

It is highly unlikely that Zerex offers anything significantly different from any other decent quality antifreeze intended for the same application. Even more important is to consider the claims of the advert in light of the
Glycol coolant is WORSE at transferring heat than plain water, but it boils at a higher temperature and freezes at a lower temp - neither is helpful in a WC system unless you're doing something radical.
Seal lubricant is fairly standard in anti-freezes, and is useful in an automotive system with a mechanical direct drive waterpump. In a standard WC system, it's useless as our mag drive pumps don't have any seals to lube.
It is true that anti-corrosives are probably a part of the Zerex blend, but you will find them in ANY good anti-freeze, so there is no special reason to prefer Zerex on that account.
In short there may be reasons to put glycol antifreeze in your WC system, but they aren't specific to any particular brand of coolant.
