Nail heads rusted through ceiling paint 1 day after indoor molding installation!?
Installed ceiling moldings with byggmax white lacquered nails for moldings. Sure - the white paint on the nail heads largely disappeared due to the hammering. Yesterday I painted over the moldings with ceiling paint. Now the nail heads have rusted through the paint and I have rust-brown spots along the entire ceiling molding. 
What did I do wrong and what can I do now to save the situation?
Tiresome problems...

I have chosen to always use hot-dip galvanized nails even indoors. This type of nail holds better than regular electro-galvanized and it doesn't rust. It shouldn't be necessary indoors, really, but it works even in newly painted damp rooms and in cold storage areas.
Ungalvanized nail, lacquer surface removed, water-based paint -> rust, maybe
Conclusion: Don't buy nails at Byggmax.
And I've also wondered about those white-painted brads (and list screws):
The only part that will be visible is where the paint is guaranteed to disappear.
What's the point really

White-painted dyckert nails work very well I think, though I've never bought from Byggmax or similar.KnockOnWood said:Ungalvanized nails, lacquer surface chipped off, water-based paint -> rust, maybe

I experience that certain water-based paints cause all untreated iron to rust. There must be something in the paint causing it. The worst example was when I bought water-based radiator paint - small spots of bare iron are hard to avoid on a sectional radiator. When you touched up such areas with solvent-based paint, you didn't need to rustproof every single bare spot. With water-based paint, you have to prime everything if you don't want rust spots.
In the basement where I applied latex paint on plank walls with shiny nails, there were brown stains from the nail heads as well. I solved it by applying a bit of rust-proof paint on all the nail lines first.
On moldings with ceiling paint, I haven't experienced the problem, but I usually fill all the nail heads first too.

Block out with knotting paint, you can make your own knotting paint by diluting regular wood glue with a little water to make it spreadable.

It is the same problem with such nails (from a nail gun) without heads, which construction companies use when installing moldings. The nails start to rust immediately. Painting over with water-based paint doesn't work.
