Thanks again to all for the benefit of their experience.

Max. width of the void is ~1/4 - 3/8 in., and perhaps 10-12 in. OAL, tapering at each end.

Use of filler will be temporary until this board and others are replaced.

Need to fill a split in an exterior board - what brand(s) of wood filler
perform well in this application after priming and painting?
Thanks.

Splits can be iffy. I wouldn't use any rigid filler, I'd use a caulk, then
prime and paint.



Caulking - that was my first thought also... but don't know
the size of the crack. Normal caulk will only work up-to
a certain size opening. Perhaps a specialty caulking ?
