yea, I think you are probably right, should have tried a small piece first or taken it out quicker. anyway,, its all yelloish now, rather use clear tubing.
I think it was Thermal chill or Thermal take or some other stuff I got from someone when I was expanding my little loop.
anyidea if I can get some in UV or something? Frozen CPU has some in Clear and Black. No other colors. I would had liked Green or something. How about ebay sources, Frozen CPU want $7 to ship out 3 foot of tubing but $36 for 5 foot.
