Fixing Countersunk Siding Nails

Sand down to bare wood, then apply wood putty, leaving it a little thick so you can sand it down level after it dries. Put a coat of primer on all the bare spots before you paint the whole thing.

Before you do a lot a prep work, check the siding to to see if you'd be better of replacing it. The fact that the nails are showing up as depressions means the wood around them has swelled.

I've never tried it but...

...a short bit back there was a guy painting inside a house being redone. Door frames had new casing and he was covering the nail heads. Out of curiosity I asked him what he was using for putty. Said he was using glazing compound. Said for him it worked well because of it's long workability and it didn't shrink like so many other things.

Plan to give it a try at some point.

I've used this product many times. It works great.
