I have a roof overhang along about 1/2 of one side of my house that I am planning on replacing the overhead. My plan is to replace it with the Home Depot flavor of beadboard, 1/4" or so thickness. What's up there now is 1x2 beadboard that has been there the better part of 50 years and is warped and twisted some. This wont be changing the looks much, just cleaning it up.
Question is, which should I use to attach the new beadboard? I have a full round head framing nailer, a 16 guage finish nailer and an 18 guage narrow crown stapler. I was thinking the finish nailer but there isn't much of a head on those nails. I think the framer is something of overkill. Stapler leaves kind of a PIA hole to fill.

Before we get into it, yes, I will be priming and painting all six faces of each piece prior to installing.
