Relax, I am sharing my experience mate. And yes, it certainly can. There are different grades of stainless steel. 304 which is the lowest grade may very well stain or rust in environments of high salinity, little oxygen and low circulation. One car I saw it occur on was an 04 STi downpipe. Clearly won't happen to everyone, but it's not impossible. Most race cars I see don't use wrap anyway so I am not a huge believer in it, but that's just my $.02.
