I have a complex fascia consisting of a 1×4 over a 1×6 over a 2×8 in a stepped fashion. We have some rot issues in some locations. With one of the worst offenders, I had to replace a 16 foot area of fascia which was no easy task as the drip edge was nailed to the 1×4 through the osb roof sheathing and the corner bevel/miters were difficult to make perfect.
Elsewhere around the house, there are a few pieces rotted but none as bad, mostly either the 1×4 or the bottom of the 2×8 in max 2-4 foot sections. As I really don't want to replace all this wood I was thinking of doing a dutchman patch in these areas using my multitool to remove the rotted material.
However, I was wondering if there was some sort of putty I could use to fill rather large areas that are rotted after removing the rot. The material would have to be rather stiff so it could be formed rather deep (3/4 inch) and sticky so that it could adhere to the wood. I was thinking of kitty hair, however, other suggestions are welcome.
Spackle and wood filler wouldn't work.

Durham's Rock Hard Water Putty is a great product. You can mix it as thick as you like using water. It sticks well, but can still be formed. Dries super hard relatively quick. Easy clean up and can be sanded and painted. The best part is that it doesn't shrink.
