Gary: I installed Thermo Tec header exhaust jackets on my '70 Spit several years ago. I have a Buick V-6 installed and there were both engine compartment heat problems (causing excess foot area heat in the passenger compartment), and close tolerences to gas lines, brake lines, oil pressure gauge line, etc.
I could not be happier with the product. A great deal of heat reduction in the engine compartment (and subsequently in the foot well of the engine compartment). When the car is running at operating tempature, you can hold your hand about a 1/4-inch away from the headers comfortably, and gives me a lot more confidence that I'm not going to have a fire or melt something unexpectedly. With regard to the rust problem, I try not to drive my car in the rain any more so don't have much experience with that. However, I just don't get it how they could cause excess oxidation. If the jackets or wraps are permeable enough to allow moisture (water) to get at the header pipe, then they are permeable enough to allow the moisture to boil off once the car is up to operating temperature. I recently had to take off portions of my jackets to replace my exhaust head gaskets, and observed no discernable difference from pre-installation.
