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?

From this I assume you are talking about filling relatively minor defects
and not trying to fill in big rot holes or areas of missing wood... I've
been using MH Patch for about 10 years now and have had good results. A
contractor associate of mine recommended it as he had been using it for many
years with good success... I believe I've seen this on the shelf on Home
Depot though I generally buy it from locally owned True Value or Ace
Hardware stores where I do most of my business.
