This is my tried and proven method for the undercarriage:
After first renting a glass-beading set-up, and getting nasty with all the removal that settles on you as you blast all exposed steel surfaces on the undercarriage -- the approach I'm taking uses this as the finish coating:

I've used it before on expensive enclosed race car trailers when I knew I'd be going through climates with chemicals on the icy/wet roads (usually making those race car deals in the off-season). The last trailer I had-- six years later still was pristine underneath.
With the Coach, I'm going to buy both some spray cans and a one-gallon pail for brushing. But like anything else, it's about surface prep. So first it's a pressure wash with a solvent (like Gunk), and then the glass-beading, and then the Brite Zinc. I prefer the finish of the "hot-dip galvanizing" look -- to the dark grey flat look with other "Cold Galv" products.
The manufacturer in their FAQ section also says you can apply it to aluminum. 1-3 mils is the optimum thickness. So-- I'll also be applying a thin coat to the allison. The attached pics shows the current look of the transmission, and the chassis battery area -- from being in a "near the Coast" location for 17 years. This is unacceptable to me.
