It doesn't seem like something you would want to wrap a whole harness in, but might work well for the ends of the mesh covering.
I am leaning towards the Tesa tape that the place racerjoe referenced sells. At least for the ends and junctions, probably not the whole harness. Time will tell.
I wrapped all of my harnesses in this loom, not just the engine harness. It's held up very well, even in the front wheel well where the headlight harness runs.
