Hi, the front steps to my house are in a damp area, Ive had to replace some wood but theyre in pretty good shape now. Last year I noticed rust spots w here the nails are. So I ground the rust off the nail heads, puttied in som e of the holes, primed with rustoleum then painted. This year the rust stai ns show through the putty and paint again. I tied to pull out the rusty nai ls but no luck, SO instead i completely ground them down deep into the wood . Is there any product can i put in there so the the rust stains don't perm eate through the putty and paint again?
Paint or product that rust can't stain through???

Bondo auto body fiiler is what i would try
It won't stand up to the weather long term, though; the patch'll eventually pop loose.
If it's _that_ annoying, fill w/ an epoxy

Deep into the wood? Is the wood something other than PT? In that case you might try bondo to fill the holes. another option would be to switch to oil paint. Benj Moore has a product called DTM. (Direct to Metal.) It's fine on wood. They just call it DTM because the EPA is discouraging oil paint on wood. Sherwin Williams also has an exterior oil paint. both products are available only in quarts.
