How much is it?Look like I could pull this off.thanks
Its ~$30 for 2.5lbs which is good for a one gallon batch. One gallon is enough to remove the nickel. I'm planning this project (R3E mb block) sometime soon though I think 1/2 a gallon is plenty enough for one block.http://www.caswellplating.com/kits/metalx.html

Yes. There was a whole commotion about this situation. EK really did not handle this properly in the first place. Ultimately, they concluded that the plating method they used was not compatible with popular liquid/coolant choices, mainly distilled. They never specified what was the issue, but a lot of speculation led to popular beliefs of bad prepping, thin nickel application, and bad machining and surface adhesion. I guess the cat was out of the bag when a few enthusiast did an independent test and found an unused never before installed gtx 460 nickel block was already flaking.
Ek finally did some right and offered to cover rma expenses and work with retailers to assist in the rma process for overseas customers (they're located in Eastern Europe). I myself was affected and my loyalty was shatter by their initial actions that I cut my losses and sold all the bad plated blocks for a marginal cost of their potential resale value if they were not affected. Initially they wanted all customers to cover all shipping expenses to Slovenia, Europe (what an outrage), then they changed their mind when it seemed they were just backing themselves into the corner even further.
Ek's last stride to correct this is employing a new nickel plating technique dubbed "EN". This new process is according to EK "exceeding industry standards" and thicker plating. This also translates to small increase in cost of manufacturing which in turn is passed to the consumer. Makes you wonder why EK nickel blocks were about $20-30 cheaper than the compitors
(pre "EN" nickel plating).
A word of caution, a lot of retailers are still trying to get rid of their old nickel plated EK block inventory. Even though EK has launched its new "EN" blocks and the retailers are charging more for them, there has been quite a few recent reported cases about customers receiving the old versions. Retailers are also turning down customers for replacements and directing them to EK. Still makes me very angry on the part of the retailers. So, my advice: wait a bit longer until the old nickel inventory is depleted(or as it should have been, returned to EK by the retailers), email the retailer's customer support to have some proof that you wanted an "EN" block, or just go with copper, or my personal preference, go with another block maker.
Most likely, some die-hard EK loyalist will be replying to my "informative/rant" post. Good luck, and again this info comes from some who dealt with this fiasco, wasted a lot of time and money, and ended up loosing in the end.
