On a traditional solid plank on frame wood boat, does the BLO/whiting/white lead/jap drier (glazing putty and white lead) putty work for puttying over nail holes and small surface imperfections? This compound isn't going to be used for seams but rather filling small cracks and over nail heads for above and below the water line on a dry sailed boat covered in paint.

Yes it will work. However, we prefer to use Z-Spar # 2 glaze or an automotive glaze called "Nitrostan" as they dry faster and sand more easily.

Is the 3M acrylic spot putty in the same category? I've had good luck with that.

I mixed up a small batch tonite and puttied it into some checks and surface imperfections on a piece of scrap 2x4. It trowels very easily but isn't runny. It began to stiffen so I added a few more drops of boiled linseed oil. It smelled wonderful too! I will check on its hardness tomorrow and see how well it sands. How long can I expect this type of putty to last in marine conditions? Exterior home conditions?

Three days and it's still soft...and I used boiled linseed oil...weird.

I have repaired hundred year old houses that had common bright nails, set, puttied over and painted and the nails were still in excellant condition.

I've seen similar. I'm just worried this stuff won't set up harder like an off the shelf product. Well, I do have the time so I'll just wait it out.

One alternative that, usually, is ready to sand in several hours on a hot day is micro balloons mixed with fast dry West System Epoxy.
I build a small dam, with masking tape, under the ding or fastening hole to keep the mixture from drooling down the hull. Once set up, it can be planed off with a sharp block plane and then sanded.

Sorry, Jay. No epoxy for this project. :):)
