a mechanic friend suggested marine lubricant. It is used on ships at sea to withstand the salt spray. It attracts grime of course, but the logic makes sense. I suppose you could use a degreaser to remove it if you wanted....

I was reading about a protective spray, from ? Have to look up. LPS3 would
probably work. I don't know how well it sprays.

I wouldn't trust WD-40 for anything but temporary uses.

This sounds really crude -- spray 50-weight oil all over the bottom and
then drive back and forth down a dusty road until you've developed a
nice protective coating of greasy filth. Granted, I'm a Californian and
we buy eastern cars for the engines, but I've never seen any rust on
parts that have received (unintentionally, of course) similar treatment.

1 gallon mineral spirits
1 quart mineral oil
Paraffin wax or bees wax (wax toilet rings are a cheap source of wax)

Mix the oil into the mineral spirits. Warm them using a hot plate and
use a grater to add wax until no more wax will dissolve into the blend.

Brush or spray onto the vehicle.
It will give a self healing coating that stops rust. It is basically a
home brew version of WaxOyl. Works VERY well.

LPS3 turns into wax. My old standby, and using some now, boiled linseed
oil. I spray it on. Can add a little mineral spurts or paint thinner if it
does not spray. Can have messy drips, so beware. Dries to a hard finish
slowly. You can spray it into lower panels and doors too. The smell goes
away gradually.

My mom's 70 Barracuda had the spray undercoating done by the dealer. It was a black nasty stuff that would drip off the car for a long time after we got it. It was sprayed inside the doors and side panels too. Holes were drilled and the gunk was applied using a long wand sprayer. That whole thing was unpleasant business. The undercoating did little to prevent rusting on the bottom of the doors and rocker panel. That was expected of car of that era. Things are a lot better these days.

Some of the black nasty stuff is better than others. Some dry out, crack,
and hold water in. I have some pretty good stuff bought from JC Whitney,
from a chemical company in Ohio.

I heard of using used motor oil. I think it's bad for rubber parts.
