I used Water Wetter for awhile and let me tell you, it STINKS!! Literally, I mean, smells kinda rubbery and altogether bad! I had a really bad leak during my test-phase and it stunk up my room for two or three weeks. Unless you're running a closed cooling system I recommend steering clear of the stuff.
