^^ they do stuff called 'twistwrap' which is great stuff though its not quite big enough for main wiring looms. i had to put a twist in it to cover everything, which is pretty hard when the loom is in situ, i had it all out on the floor so it made my life a bit easier. advantage is you can easily open it to get to the wiring, and its not sticky!

ebay is a good source for loom tape though if you want to go down that route.
