Using wiring harness tape to fix the cracks in the wheel discs
Wiring harness tape is very sticky, as it’s meant to adhere to dirty car wiring, and very flexible, far more flexible than electrical tape. It’s more like hockey tape but a finer weave and stickier.
So it keeps great contact around the curves of this. The fiberglass tape I have wasn’t flexible enough. I think just long straight cracks it would be the best choice, but for these stress spots around the valve hole, I needed something more flexible
