There are 2 drawbacks to using Fluid-XP. First, the inside of clear tubing looks terrible after about a month. second, when I removed a section of tubing after a few months of use, looking into the end of the tube I could actually see raised clumps of deposits, similar to sand banks in a river bed. I don't know if this coolant would work very well with any blocks that have small holes, unless the pressure created by the design of the block would be enough to keep the flow paths open.
Cathar-Have you run across this yet? I was drooling over your new block, but wouldn't try it with Fluid-XP without your input.
My camera isn't able to focus close enough and the flash washes the detail out, so no pics. Is any one using this coolant able to take photos?
