OK. Here's what he said ....
"I have heard some news today about the the FM Mustangs being delivered to Aus that the under floors have been steam cleaned too aggressively to meet Australian Quarantine so much it has stripped the paint from the underside.
This has supposively caused them to rust (due to being bare metal) enroute to Australia so when they arrive Ford just quickly spray them with a can of black paint to cover up the rust.
Can anyone confirm this has happened to their FM Mustang, supposively its a messy job and quite obvious overspray on mufflers,gearbox etc.
This news came from respected Ford aftermarket performance place here in Melbourne.
Why should they need to blast clean a new car coming from the factory??"
