Nope. Drive it like you stole it.I recently purchased a 2017 mustang v6 convertible and noticed the drive shaft looking a bit rusty. There are no drivetrain vibration issues and was not sure if the rust should be removed and treated.
Thanks Nightmonkey. I just purchased it and plan to keep for awhile and like the idea of stopping further rust from accumulating. Appreciate the idea and link.You could put Owatrol oil on it and it will stop the rust.

You can also mix a suitable rust inhibitor oil yourself.
It won't look much better, but you won't have progressive corrosion there anymore.
Of course, it's only worth it if you want to keep the car longer.
