FWIW
Here is the MSDS on Hydrx:

30-40% EG
While I do understand the risks of EG in general, I always assumed that most of the "Coolants" were some sort of glycol base. Is that wrong? I'm not sure, most don't really describe the contents that well. I have used Hydrx myself when I started water cooling and was generally happy with it. I don't use it now, but I also don't run anything plated long term.
Maybe that is bad advice to continue using the block. I have no experience, but I haven't seen anyone show that it leads to problems either...all speculation that somehow flake will damage the pump or something...haven't seen it yet though. I think the block is a natural filter to prevent that myself, but again just opinion/speculation.
In the 1980s Honda came out with the "All Terrain Cycle", they were great fun machines and opened up a new sport. However using them as with most offroad vehicles included an element of risk. People got hurt and called them death machines, they blamed the manufacturers and eventually made the government ban their production. The machines did not operate themselves and the machines did not buy magically show up in peoples garages. Like any motorized vehicle, there are limits and people can learn to operate them safely if they take the time to learn and understand and operate within those limits. Unfortunately human nature and blaming others is where that one went and a good example of poor ownership and general human nature.
Here we choose weather or not to buy plated products and we choose what sort of coolant is run within them. That's all I'm saying, it's our choice.
Just understand there is some risk there is all running plated products..just like there is risk running tubes of water around your computer..
With plating I think the risk is mostly cosmetic, so pretty darn low.
Anyhow, sorry to stirr the box of bees. I haven't had any personal experience with corrosion of plating, so just my unaffected opinion here after reading countless threads on the subject. I don't think it will resolve itself and just trying to inject some realism about plating in general...
