I had tried the tree protector that is made from fabric with brass eyelets. After a couple or three months they rot out. What do you use to protect trees when attaching guy wires to keep them straight?

I have used 1/2 in foam pipe insulation successfully. It is malleable so that a short pices under the wire will stay in place if the wire is cinched a bit. Pretty obvious it will not scar the trunk.
