Anyone try this stuff? I just put some in my Marauder (4.6L 32V for the same reason metroplex mentioned about the inefficient cooling on cylinders 6,7,8. Already had the cylinder head replaced once.) I live in the Pacific NW and this stuff is made in Redmond, Wa. I've included a link and a link to tech info. (Supposed to be better than Redline's Water Wetter)
