I use "Zinc Mate", which is just a spray bomb of Zinc paint. The can says
95% pure zinc is inside, and I beleive it... if it sits for too long you
have to shake the dickens out of it to get it to spray like paint.
It runs quite a bit and the nozzle tends to clog. But once it works, it
goes on, and I haven't seen any rust (yet!)
Other trade names are "Galva Froid" and "GalvaCon" (Galva Froid may be
different)
There are no problems applying (laquer) primer and primer-surfacer over
this paint. Whatever you get, be SURE to test it on some scrap metal
BEFORE putting it on the car!!
I also use Tremclad/Rust Coat/Armor Coat (depending on brand) rust paint
to cover up anywhere on the car that won't receive a finish coat (like the
inside of the fenders)-- I will not be painting the entire car body color,
as stock. The inner fenders will be undercoated, so it won't matter what
color they are.

Do it! Most Rust eaters don't work well on clean metal- if you put Rust
Destroyer on it, put something else on top. I think a major ingredient
for rust-eaters is Sulphuric Acid, which is water-soluble. So any
condensation inside your rockers could remove it (just a guess... never
tested it!!)
My rockers will get a royal treatment- Zinc paint, rust paint, undercoat,
wax-oyl, whatever else I can find to spray in there!!

For temporary protection, use WD-40. That's what it's made for- but it
only lasts about a week (less if you work with the metal)
For metal parts that will be stored for extended lengths of time I apply a
thin layer of cheap grease. It's messy but it keeps it clean and
rust-free. I did some exploratory surgery on one of my rear fenders last
year and it's been sitting ever since (I got depressed ;-)) I will be
pulling it out of storage soon to repair it. The last few repair have
been horrible- new metal stacked upon old- not recommended.
