If the manufacturer or the customer applies a thick heavy undercoating I think it can make a big difference. It's robust enough to resist the abrasive nature of the salt, at least for a while.
The thing is I don't think manufacturer's like adding products like that as it messes with the fuel economy results. It's actually quite heavy, despite being just a "coating"

It also says it protects from rust despite abrasion.
