Actually, saw Gordon's recommendation above just now. He's likely right. The key is phosphoric acid. Don't panic, it's benign and works fast.
I like the brand OSPHO but there's others.

okay got it. thank you.
so both of you are saying that those products are available at marine supply stores? or, can one go to a home improvement warehouse and get it?
kimo, we did it just like you, but for some reason, it didn't work. maybe the nails weren't pounded in enough. they still bled and we're now trying to remedy the problem again and then painting again.

Kani Lehua, the Por 15 does the same basic acid treatment on the rust as Ospho, but also gives a bullet proof coating on what's left. Kona marine is the only place I know who carries it, Oahu guys had to order it from there and it can't ship by air. Followed by a sealing primer like Kilz.
You couldn't live in a much worse place than Kailua for rust. Also, for the treatment to work, each nail must become visible, and most paint and caulk removed from the hole for it to work. And the word is stain"less", not stainproof. Good Luck!

i know, i know--rust, rust, rust! one can actually "gather" salt in the tracks of our new windows. corrosion is happening. mind you, i clean the screens and windows at least 2x/month. we even find rust on our clothes and that's with keeping the closet doors open.
i'll have to check into both products that were mentioned. know any canoes coming over from kona to our kailua? how'd they get it here, barge?

Ospho can generally be found at an auto parts store. I'm currently using an off brand called Purple Power. My only caution would be to test it on the surrounding surface. It will damage some materials and finishes. When treating nail heads you might want to be very careful to restrict it to the nail. I have also used it as the finish on knives. It works fairly well. After making it totally in the white and then cleaning and degreasing, it helps to leave it outside for a few nights to get an even coating of fine rust, then ospho it. After it drys, I recommend a baking soda rinse and then a fresh water rinse and then an oil coat after it drys. I'm thinking of trying the method on an old gun barrel. Kind of a poor mans phosphate finish.

Agree with oink on all but oil coat over ospho (unless he meant oil paint) like kilz sealer. Any oil whether 40wt or WD40 will not allow the final caulk and paint to stick!

No oil for the nails. The oil finish would be for the knife or gun which wouldn't be painted. I shouldn't have mixed the topics.
