So many things wrong with this thread...OP has clearly
stated he wants dyes, not colored tubing, and is willing to take on the risks and cleaning it involves. Ergo, you do not
attempt, on multiple occasions, to dissuade him to do so. Dyes may not be for everyone, but if he wants a good quality dye for his loop, you answer the flippin' question and that's it. That's what this forum is for.
OT, three huzzahs for Mayhem Dyes.
Product page for the blue dye: http://wcdyes.com/shop2/10ml-mayhems...deep-blue.html
Couldn't find a US based store that sells it, and from the popular computer supply online shops only FrozenCPU seemed to have any Mayhem dyes at all.
EDIT: The Google Shopping results for "mayhem computer dyes" returned all of...4 results. Three of them from FrozenCPU (none of them blue), and the fourth was completely unrelated. You may be out of luck in terms of buying these in the US.
EDIT 2: Also, if you're going to get PT Nuke, make sure you get the one specially for loops with dyes in it (PT Nuke CU, as opposed to PT Nuke PHN): http://www.petrastechshop.com/pepcobi1.htmlEdited by crazyap7 - 7/22/11 at 11:27am
