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?

If you're willing to go to so much work, seriously consider removing the nails with a good pry and replacing them with stainless. Cedar is quite hard on galvanized, and putty will slow but won't prevent corrosion from leaching out -- worse, putty will look bad.

You have fire insurance. I suggest that you douse the place with petrol and fire it up....that way you would have time to help your friend Walt work on his new house. As for another scrubbing...I hear that Walt still has a blister from the last one.
