Yes. I try to avoid it.
My 15 yr old van is pretty much rust free because of three reasons: not much use (44,000 miles), garage kept & rust prevention coating.
The original owner of my van had Krown Rust Control applied and I continue that practice with Rust Check (Krown not available near me).
Rust Check and Krown are thin oils that are sprayed on underneath and in door panels etc. They continue to spread for months after they've been applied. The oils displace water and form a protective barrier. They are messy at first because the excess oil will drip on your garage floor or driveway. And, it is messy when you work on the vehicle because everything is coated in the oil. However, the parts look new under the oil.
I get the car done annually at a shop and I use the spray cans of Rust Check for touch ups and when I put on the winter rims/tires, rotate the wheels etc. If I install something on the van like a hitch I coat the areas & parts involved before and after the job. I didn't have the van done this year because I checked underneath in the Fall and everything is well still well coated in oil.
I think the thinner spreading oils work better in this climate; near the ocean and salt on the roads in winter. I've had cars with thicker, tar like rust stuff that did not prevent rust. Around here, it is the first thing I'd get done on a new vehicle.
Without hesitation, I'd recommend Rust Check or Krown to prevent or at slow down rust.

, otherwise B's are just to expensive to shorten their life, if you can help it.
