You know what I find amazing, that I have not seen one bad thing on nickel plated Koolance blocks yet (other than the steel plugs 3 years ago) even after all this happened, and EVERYONE OF THEIR BLOCKS IS NICKEL PLATED. I think I'll pass on EK products from now on, because instead of blaming the plater (100% is their fault and no one will convince me otherwise), they try to blame the coolant, when koolance nickel plated blocks have had 0 problems with the said coolants + additives. So EK's solution is to send the blocks back to the SAME PLATER, to get replated by the same process that previously did not work.
