Review on Electriduct 0.5 inch Heat Shrink Braided Sleeving - 50 Feet by Dwayne Shavers

This is great stuff to clear up some confusion. The size listed before shrinking is the diameter (round) and not the horizontal width. I've only used it to protect my car's seat belt and it worked perfectly, nice and tight with no chafing. I used a heat gun to shrink, not a hair dryer. I was so impressed that I ordered 3 more sizes.
