[quote author="Scenaria"]I feel stupid for even asking about this but... does anyone know of a source of wire sleeving that can be heatshrunk? with glue on the inside I suppose... kind of like what they put on stuff like monster cable cables...[/quote]
Unless I'm much mistaken, you just want regular old "heatshrink tubing", which comes in a variety of sizes and with/without glue. You can even buy it at Radio Shack. Just find a size that can fit over your wire, and heat up with a cig lighter or a heat gun. The stuff usually shrinks to about half its original diameter. Don't bother with the glued variety, unless you need waterproof connections.
Wonderful stuff, couldn't live without it.
