You wanted to cover a galvanized wire. Not sure if this will help but
it is certainly an idea. They make wire loom plastic which is slit so
it will slip right over the wiring. I have seen this in a variety of
diameters. If you can't find the diameter you need at your local home
improvement store, you might try a high performance automotive store
like summit racing... or google 1 inch diameter wire loom. Here is the
catch... it's plastic. If yer lil guys like plastic I am not sure where
to go. Hope this helps!
