Saw this on rec.autos.tech. Since I have a ton of parafin wax sitting in
a corner of my garage (it's a long story), I may just try it out. Seems
like you could put this brew together for < $20./gal, which is definitely
worth it if you're doing support vehicles as well.

It's pretty simple, really. Take a pound or so of parafin wax and grind
it up with a cheese grater. Soak it in a half gallon of mineral spirits
until all of the wax is dissolved. This might require allowing it to
sit in a closed container for a couple of weeks. Stirring will cause
most of the wax to dissolve, but soaking should take care of the rest.
Generally try to dissolve as much wax as the mineral spirits will hold.
After that, dump in a couple of pints of mineral oil ( less of a smell )
or non-detergent motor oil.
If the mixture is thick, thin it further with more mineral spirits until
it is of a sprayable consistency.
Buy one of those cheap engine sprayers at the local auto or tool store
that carrys air tools. It is a metal wand with an air fitting, a spray
button and a rubber tube to dip in whatever you are spraying. Rent or
borrow an air compressor.
Safely elevate your car so that you can get at the underside. Spray the
solution onto, and into every crevice, crack, hole, and surface you can
get to. Then let the excess drip off. The beauty of it is that the stuff
will soak into any rust spots. The rust seems to hold it like a sponge.
It will also bleed into the smallest cracks and folds of the body and
protect there, too.
All you need to do is repeat this every year, and rusting should be
greatly reduced.
