Read the article HERE first; then post your comments below about your experience or knowledge.

I'd like to see a decent debate here; NO FLAMING!

Thanks guys.

I agree with Darthripley about not being able to see a crack developing. I experienced that with a wrapped turbo exhaust manifold.
I would take note of the climate you're in--I personally wouldn't use it in a high humidity climate such as where I live in South Florida.
Might also depend on how often you drive the car...just a thought, but if the car is not driven often or is stored outdoors, it would be easier for exposure to moisture from rain and snow to occur.

sofla is exactly right about the humidity/weather elements causing probs to develop faster than in drier climates.
when we got our 4agze motor it had a nice quality wrap on the header and the b-pipe (midpipe) and after removing it we found the welds around the flex pipe were rusted with cracks and there was a crack on one of the header primaries that we had rewelded.
we have no way of knowing how long the wrap was on but after everything was repaired we had it ceramic coated and its been fine for almost a year now.
