Here's the ebay thermal wrap sold by 3xjacks and made by JC performance.
It's listed as 1/2" x10'
It's about 3" wide has a foil backing over a fiberglass wover material and has velcro strips sewn on the entire length to roll/close it. It is about the size of a dime when the velcro is aligned properly, But I think you could adjust it a little either way if you're creative. I may even wrap my fuel line near the engine
