gotta admit, if they sold them looking that good i would of bought one. corrosion should not be a problem to the exterior of any waterblock if you know what you are doing. Ie, go out and buy a anti-corrosion polish from a car paint store, the kind you can get for chrome work etc. and give the block a wipe over every 6 months or so. as for me, i have never needed to use any kind of anti-corosion compound on any of my waterblocks, and they are all just as shiney as the day i brasso'd them.
