OK, time for some tough love:

The plastic wire loom doubled up looks like it was installed by DD. It's jacked up. I'm sorry, but somebody had to tell you. And a friend is somebody that will smile and say "nice job". A real friend, however, will tell you when you jack something up.

This is what I had in mind:

Heavy wall fiberglass sleeving, fiberglass braided sleeving

No idea where you can find it in less than 100' increments, but you got some googlin' to do boy.

Wannabe...

PS, the proper way to thank a real friend is to buy them lunch. I'm just saying.
