Is there any good way to coat rusted nailheads that will then take paint? Someone did not use galvies and now I have this problem.

A rust-converting primer may be the best choice.
I have the same problem on some hardie siding on my own house. House is on the beach and some of the nails are cheap hd galvies that didn't get painted for a while. Most of the nails arenot rusted. I have some spray cans of rust inhibitor I was going to use but was wondering if sanding the nail head was needed. Thought I would jump in on this thread to get extra info.
I don't know, but I read here a good while back about someone having the same problem. I don't remember much about what was settled on as the best remedy, but someone mentioned that an experienced old-timer told him 'aluminum paint' was the sure-fire solution. I have been wondering to this very day what and where to get it, because if it works I want some.

True. IIRC, which I often don't, it was something else.
I've got some rusting galvies on my porch that I just may try it on. Been holding out for that magic moment when some kind of obscure aluminum paint product I've never seen before gives me that "Ah-ha! This must be it!" feeling.
But it really, really, could be the Rust-Oleum stuff.
I recommend the person asking this question NOT settle on using this unless someone else backs this up with a no-doubt affirmation.
Bumping this up to get some affirmation on aluminum paint and not sanding rusted galvanized nails.
Just about any non-latex primer will work. I've had good luck with shellac-based primer/sealers (like BIN) in a spray can. In fact, it works pretty well without even removing the existing rust.

I've dealt w/ rusty nailheads a lot and one of the many rust inhibitor primers is the way to go
I reach for the ones that say will even cover rusty spots and don't rub them clean
if weather is halfway decent it will dry within 10 minutes and then give them another shot for good measurejust used aluminum paint on a closet at my in laws place ( it was up fpr sale ) - master bdrm closet where no matter if I used Bin w/ shellac primer or another heavy oil base a deep bloody red kept migrating or wicking through
yes I was imagining all kinds of evil doings on the other side of those walls
anyway aluminum paint was recommended to me so I picked up a gallon and Eureka - no more blood coming through the wallsif someone wants I'll go down to the basement and get brand name & specs

I had this same problem and used a product similar to what Rooster posted, from local hardware store. Then primered with Bin and painted, 18 months and all is well.
My situation was about 50 nails spread throughout, on my trim.

The bigger question for me may be about sanding. Are you sanding more galvanized from the nail surface and making the sanded area more vulnerable to rusting through the aluminum paint or not.
Maybe what you need is some galvanizing paint.

We use this after welding on galvanized steel.
I would sand, neutralize and paint. However, when I had my problem with bright nails, I just used a Bin primer not galvanized paint

Bumping this up again to see if anyone knows if it would be better to sand a rusting galvanized nail head (possibly removing galvanization?) or not sand it and paint it with aluminum paint.
Again, I'd not sand, and then use a rust-converting primer.

No, after the primer I'd just use whatever paint is used for the siding.
