Ron,
First, sand down the nail heads with 100 grit sandpaper. Wipe them down
with a solvent to remove dust and dirt. Mask off the surrounding area and
apply a red oxide primer (two thin coats are better than one thick one).
Allow this to dry thoroughly and then caulk the edges of the nail heads to
the siding, then paint the siding.
OR
Set the nails a little if needed and caulk over them. ;-)

I've had the best luck painting over rusty stuff with Extend, a product by
Permatex I've found in auto parts shops and Home Depot. It's a rust
converter, not just a primer. No sanding, just scrape off any big lumps or
flakes. Slap on Extend. Heavy rust could take two coats, but it dries fast.
It turns rust into a flat black coating that doubles as primer. I first
started using it on car stuff, then eventually used it on everything,
including gardening tools that get wet all the time. I tried several
different brands - Extend is THE one that works. Oh - get the bottled
version and SHAKE it thoroughly before brushing or sponging on. The spray
does NOT work nearly as well.
They buy this stuff by the barrel (literally) at the Palomar Observatory,
where the painting bills used to be horrendous because of moisture and wind
whipping it off constantly. Extend did the trick, made a stable enough
undercoat to keep paint on.
