First clear out all the soft and rotten wood that you can. Then, use minwax
woodhardener http://www.minwax.com/products/woodmaint/hardener.cfm . Then
fill with their wood filler which is similar to plastic body fillers like
Bondo (which I use as much as their filler). If you don't clear out the bad
wood, the filler may eventually fall out.

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
