Ive seen a couple threads where people have dyed their psu cables black. Im thinking about doing this and havent been able to find any tutorials on how to. I was just curios to how you guys do it? Thanks.
Get a big metal container (like a pot). Put in liquid Rit Dye and water (not too much). Heat up on the stove until its about to boil. Turn the heat off and then dip the cables into the hot mixture and let em sit for several minutes, constantly mixing it so no damge is done to the shielding from the hot bottom.
Remove, and rinse off...
Rit advises to put a cup of salt into the mix for penetration but I'd definately not do that for cables.
I've dyed a ton of vintage BMX brake cable housings with the procedure above and they turned out great. Same for vintage plastic BMX seats.
