be a redneck and like get some pink insulation and use the insulators secret weapon- Duct tape
I think we've all, at one time or another, tried using duct tape in a warm engine compartment to cover holes or wrap a hanging wire. It just doesn't stand up to the heat. Usually the outer layer of the tape disbonds and the colour fades.
Now with the alumium foil wrinkled multifaceted reflective look of the Reflectex wrap and the aluminum tape, it stays looking the same for a lot longer time.
I suppose, it'* all a matter of personal tastes. I think the silver reflectex wrap looks pretty good. The only weak point is the tendancy for the tape to disbond at the stress points due to engine flex.
If this material is applied to a static part, it will hold up, look good and be effective at insulating for a long time.
My plan is to eventually fab up a stainless box and insulate it with silver wrap material. The key will be to incorporate a rubber boot for the connection from the box to the pipe, to allow for engine flex movement.
