Interesting. I was told by someone on the evil forum that these products eat coolant seals. Water Wetter was mentioned specifically. Any thoughts on that?

That would actually seem counter intuitive. all manufacturers coolant like GMs Dex-cool for example, is formulated specifically to lengthen the lifespan of their seals and other rubber components. however, all antifreeze if not changed periodically will turn acidic, and start to eat away at these things and even metal, and that is what i suspect is happening. The only real way to test this is to place a new seal in some solution and come back after a few months to see whats happened. My guess would be not much. In my experience seal corrosion is mainly because of an owners inattention to basic maintenance. i flush the coolant about once a year while some people dont believe you ever have to, they just keep topping it up when it seems low, which is a terrible practice.
