Many years ago I used soft brass wire to make nails on the hull planks of my Le Mirage. After after inserting and cutting I filed them first down to the wood with a fine flat curved file, like Paul mentioned. The front one on this couple of files:So, my question became what to do first, install the copper nails then sand or sand then place the nails.

After that it was no problem to sand the nails together with the wood.
