If Vanagon exhausts behave anything like motorcycle exhausts, be aware
that wrapping may accelerate rust on your pipes. Not sure why, I'm
pretty non-technical, perhaps something to do with condensation
settling between the wrap and the pipe? Can anyone elaborate on /
disprove this statement? Any preparation necessary prior to wrapping?

Cheers,
Mike.
