I was gonna say POR15, too.
There's no mystic science to why they stopped painting the rear axle and other suspension parts. These are heavy materials that are not in danger of rust-through, like sheetmetal would be. It costs money to paint the axle housing, yet in only a few years road use, salt and weather have stripped all the paint away. It makes perfect sense to reduce the costs by skipping the paint.
You want it pretty? Paint it. But be ready to do it again sooner than you think.

I hate that too, I dont understand why car manufactures cant just take the time to put a thick coating on everything metal on the bottom of cars.. BUT you could always just buy a car from here in the desert 
The 06 Mustang I just bought is seriously as clean as a brand new car underneath.. Not even a hint of corrosion

Wire brush a little the best you can if you want and make sure it's free of oil or water and go for it.
For those wondering...
This stuff will not stick very good on clean bare metal so if you have only a few spot with surface rust, it's best to treat those spots first with regular products (like OSPHO) and prime the whole thing with epoxy and then throw some paint on it.
Or............if you're like myself, wait about a year and it will be entirely coated with surface rust and at that point, just brush on the POR15 and reward yourself with a cold beer.

@ Pascal...you just wire brush this **** in and don't have to paint over it? This seems uncomprehendable...How does a product both remove rust from unpainted metal and leave a painted finish?

I understand it bonds with the rust and changes it's properties, but how long does this last effectively? Any ideas? Will it need to be gone over again in 3yrs, 8yrs?

I can see where this little job can come out looking nice, but I'm too lazy to do something like that just so somebody who is taking a chance of getting exhaust-burnt or inadvertently run over won't come complaining to me about it or whine about needing a tetanus shot.

And yes, it bonds with the rust as long as we're talking about surface rust, not rust through surfaces. Big difference!
Brush one coat for saturation and apply another one 20mn/30mn later (this stuff dries slow) for durability and finish.
Once dry, it looks glossy and turn semi gloss with age.
Also, it is not user friendly, should you feel the need to coat it with paint later on.
This stuff is really hard to sand
