Re: Exhaust questions: paste, wrap, needles

[Alan Lemen <ralemen@cableone.net>]

Joe, true about the heat and moisture. Since I live in what in 
classified as high desert I don't really care so much about moisture and 
rust anymore. But I would agree James lives in a damper climate. Mind 
you he is still drier than some places.... I would never wrap a mild 
steel header or anything mild steel unless of course I didn't care and 
could afford to replace like some racing teams.

James, I had assumed that it was not mild steel. Mine is stainless 
steel. I have no idea what your one is made from. An alternative I have 
heard are coatings that take the heat, stop the rust and act as a 
thermal barrier to some degree. Not sure what is available in the UK. 
Trouble is that I am sure they cost more than the wrap. Also you can buy 
cans of spray treatment from the wrap manufacturers that seal the wrap 
from dirt and moisture. No idea how good they are though.
