headers wrap question

Friend used it on some headers. Danged near burnt the car to the ground because of it. ATF cooler line leak sprayed ATF onto the headers. Couldn't put the fire out until his passenger spotted a nearby garden hose. On removal he found that the rust errosion of the headers had been accelerated by the higher heat of the wrap. ATF lines got replaced with industrial hose & JIC fittings.

Seriously doubt that he had late timing as he was then one of KA's smog referee's and he spent a lot of his open time with his car on the scope & three gas analyzer refining the tuning of the car. Tune and then test up & down a curvy mtn road nearby.
