The nails on my pressed-board wood siding on the house I bought a few
years ago have become countersunk.
Maybe they weren't nailed into the studs. Maybe they started
countersunk a little bit and moisture has done its job. Maybe the
siding is lousy. Whatever.
What's the best putty/spackle/caulk to use (after the pressure washing
but before the painting)?
Anything else I should know/do/consider?
