Under Coat
The last Ford product I purchased was a Bronco 50 years ago and it rusted out really bad.
While I was looking at a 2021 Ford F150 XTL SuperCrew they told me the body was Aluminum so,
I purchased it. They also tried to sell me more addons which I said no but maybe a little later.
I intend to keep this vehicle for at least 10 years, anyone have suggestions and cost?

The only ones worth doing are the oil-based kind like fluid film, krown etc. Need to reapply every year or two, but pretty cheap each time, and lots of people do it themselves. It's the frae and suspension and other underbody parts that are most crucial.
Don't get anything that's rubber or asphalt based. Those will trap moisture.

Regardless of the brand, you cannot and you shouldn’t compare a vehicle that you purchased 50 years ago to any vehicle that’s produced today.
Modern vehicles have totally different and better steel, aluminum, and metallurgy.

Not Comparing
All I was saying was that having a bad experience with Ford kept me from even looking at purchasing one again. Not comparing just stating it kept me away from Ford all that time and have had 20 different vehicles since then.

I don't know much about Woolwax or the other lanolin-based ones vs petroleum oils or whatever Krown and Fluid Film are. Woolwax claims to last longer. Could be true, I don't know.

Aluminum does not rust. What you see is not rust, but pitting.

I’ve read WoolWax is thicker than Fluid Film. Both are great products. However, some applications are best for a thinner product while others benefit more with a thicker product.

What would be the recommendation for an eastern NC/VA climate? My truck will see salted roads once or twice a year and a trip down beach at the NC outer banks infrequently. Mainly I deal with a 1 mile long rock road, which gets a bit muddy, eastern VA dirt trails around fields to tree stands, and red clay mud from summer trips to the NC mountains. I looked at a used 20' which had load helpers installed, found sand behind the rocker panels, and noticed a disturbing amount of surface rust starting underneath the paint on the frame. It was flaking a little along every edge. Granted washing underneath your truck is extremely critical after each exposure to road salt (yes VA uses salt) or beach trips, but often enough with my last daily drive I only had time to do the underbody option at the carwash several days after, before I could find a weekend to power wash etc.

The lanolin based products do not fill the cab with a sickly petroleum smell. At worst it will smell a little wool-ey for a day or so. Nothing bad at all. Completely non-toxic, but you probably should wear a dust mask during application just to keep the grease out of your lungs.
Never dries so the underside of your truck probably collects a hundred-pound coating of sand on top of the woolwax. That just helps protect it, but you will need a significant supply of rags when you do any work on the undercarriage!
