Header Wrap, what do you like

how do they retain moisture if they are always hot? I had some on a garaged car for 4 years and the headers faired fine. I used stainless pipe clamps on mine to secure them

I'm thinking it has to do with "high" humidity areas. you know where swamp cooler just don't work, and when you step out of the house, you feel like you just stepped into the shower.........LOL

We will see, when i unwrap them. But what wrap has fallen off, don't look any worse for the wear.
