I had the same thought initially, but my local AutoZone only had edge protector meant to slip over something much thicker (a door edge) than the hub cover. It was quite large and I tried it, but it would not stay "closed up" on the cover, and was very obvious so I removed it. The tubing I used is clear and (IMHO) barely visible. I have pointed it out to others and they have to actually look hard to see it.
If someone makes a smaller material in chrome it probably would be easier and look even better. But what I found locally just didn't work for me.
