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

Home Depot sells a product IIRC is called RockHard in the paint department.
Mix with water and apply quickly and be sure to remove all loose rotted
material. This is a temp fix that can last for several years but my
experience is that you will have to eventually replace the board.
