I Googled this as you suggested and it appears to be a really nice product.
I noticed that the minimum cable diameters for the different products in the
series match the most common feedline diameters that we use, including
hardline. Very nice!
Thanks for the tip Jim.

away like a grease pencil wrapper) and the tubing shrinks down over the
google for the name of the stuff, and you can find the datasheet on 3M's
