Thanks, guys. Well they're painted black and the car hasn't really gotten wet yet, so no rust; but it might matter if there was cause to replace one of them. By magnetic I meant that the material attracts a magnet. Even the weak magnets of a foam ding protector will stick firmly to the driver's side heat shield. On the passenger side, not even a strong magnet will stick. Doesn't seem that likely two different batches would be used on the same car at the same time. Anyone else have a mismatch? Visually there's not much of a difference.
