My house is 20 yrs old, in the Central Valley of N. Calif. I've got a couple fascia boards (2X6 fir) that are showing age: the ends have split a bit and look a bit ragged. There isn't' any major rot or deterioration yet.
I plan to srape the paint off, sand smooth, fill the gaps and rough spots, prime and re-paint.
Q: What is the best exterior wood filler for this use?
Thanks a heap -Zz
