I’d like to get something in a rattle can that goes on EASY. I don’t have to deal with real salt in the winter. A spray brine on the road. Maybe 2 or 3 times a winter. Not much snow. But truck is new. Nissan Frontier. What’s light and easy to go on. I have used Fluid Film in the past. It was messy. But did do its job on a ford I had. Power Blaster go on easier ? I see Lowe’s actually has both. Wardawg.
 
I've heard Waxoyl is very good for brand new vehicles that have not been exposed to a winter road treatments yet, though I haven't tried it myself. Frankly, I've had such good results with Woolwax that I just continue using that.
 
Surface Shield.

You have some choices with a new vehicle. The products that have some wax along with oil provide better protection for new vehicles. The oil based ones are better when the vehicles is 6 months to a year old.

There are a lot of places you need to get to (like inside frame channels) where you need a long wand with several jets to cover 360 degrees as you move the long wand in or out.

I would suggest you get it rust treated at a shop and then do then do the annual touchups yourself.

I like NH Coatings. But there are other products. Most will be a little messy.

Looks like you are in NC. May not be that many shops in NC. I had trouble finding one in DE. There were plenty when I lived in NY
 
I’ve used Fluid Film and surface shield on all every truck I’ve had with great results. Very similar products. The Surface Shield stinks a bit less but costs more.

I’ve got no experience with Waxoyl or Krown but they’ve got lots of satisfied customers too. I’d be more than willing to try them.

Just avoid any rubberized, hard, Ziebart-type undercoatings.
 
Noxudol. Specifically Noxudol 700 for the cavities and 300 for the undercarriage. Comes as a liquid can for your own spray gun or in an aerosol can. 700 is a bit thinner and wicks and creeps into the nooks and crannies and stays there. The 300 is thicker and holds up to undercarriage stuff better.

It dries like a firm wax and has stuff in it that attacks rust and corrosion and renders it inert.
 
The main point is to use some product designed for protecting the undercarriage of a car/truck. There are products designed to protect metal items in a crate. But the undercarriage of a car with the road spray and salt brine is a much different environment. Most product creep so if a rock or ice chunk scrapes some of the product off the remaining product should creep over exposed spot when the weather is warm.

There are areas that will need some kind of wand shoved into a cavity to coat the cavity. The shops know how to do this. DIY will need to figure it out. Some shops drill a few holes, spray in there and put a plastic plug back in the hole.

Some use a black color on the undercarriage and a translucent amber color in other areas.

NH Coatings has an option to add a mouse repelling smell to the product. Might be good if you have any crafty mouses looking for a warm winter home.
 
I’ve been a Fluid Film fan for a long time. I tried Surface Shield this year and I like it a lot. Fluid Film seems to stick longer. Surface Shield doesn’t get faded and brown with dirt. Surface Shield smells more tolerable as well.
