Heat shrink tubing

Heat shrink tubing is perfect for automotive wiring. The <a href="http://fluorotherm.com/Properties-PFA.asp">PFA properties</a> of heat shrink tubing made by fluorotherm.com is hard to beat because it offers chemical inertness and vibration resistance.

I think heat shrink tubing is

I think heat shrink tubing is awesome too !
