[V12|V12]

Umm I've been WC'ing for about 5+yrs and I've never had a leak, using marine quality grease+vinyl tubes and some screw type hose clamps... You don't need to check stuff every week, just do a test with stuff out of the case and look for weak points, then you should be fine... I went as far as coaing my mobo and other cards with clearish (thick) urethane coating, so if in the even if the unthinkable happens, I can simply shutdown and dry the parts off and get back to doing my thang! After a while, when you've tested and KNOW that stuff is not going to leak, then you won't even give leaks a second mind... Besides, if you use the proper quality tubing and grease/clamps, there's not enough heat produced in your system etc... to even bother the materials. And that Jet dry stuff... Don't F around with that. I came up with the DYI-additive idea a while back with VERY small amounts of Lysol and BigBen suggested jet-dry, they both work as a surficant, but Jet-Dry isn't made for anti-bacterial purposes and if even added minutely over a drop, will cause foaming in a high flow system, least from my experience... I'd leave it alone. As long as you have a nice 1:7 or lower mix of anti freeze, stuff should be fine, if not get some Redline water wetter.... good luck.
