I wrapped my headers last summer, as under bonnet temperatures on my VHPD SLR were giving problems with the engine cutting out after spirited summer track day laps in the absence of a cool down lap. I just wanted to cover the first bends and stop before exiting the engine bay. The wrapping was simple - worth watching few Youtube videos, buy extra stainless steel cable ties for mid-point security, don't rush and be prepared to re-start. The high temp spray paint is critical to harden and secure the material, I did an entire can on a four branch header - but could of easily done a can and a half. The car hasn't stalled in hot weather, you can't see the wrap from outside of the car, and it's not un-wound. Hope that helps - Rob.
