The builder used galvanized nails on #1 cedar (horizontal) siding on my contemporary house. Needless to say every nail head exposed to the elements has a ugly black stain under it.
Two years ago I used a full strength deck wash product and left it on the surface for 1/2 hr. and scrubbed with a soft brush with pretty good results. A coat of CWF was applied and the manufacturer said I would not have the bleeding problem again. NOT! Two winters later and it looks just as bad as before.
Am considering setting cleaning the house again, setting the nails, puttying the holes and finishing with a Pentafin product. IS this approach advisable? What kind of putty would I use?

I believe stainless nails should have been used. Putty may work but you may have trouble getting the color to match. I've used both Elmer's and Plastic Wood ....try mixing the Penofin with the filler before you apply it. Pick an inconspicuous spot to try first just in case you don't like the results. If it were me, I would try to gently remove the galvanized nails and replace them with a slightly longer stainless nail. It can be done providing the old nails are not ring shanked or coated and you have clapboards.
