Getting ready to put some Olympic oil-based transparent stain on my exposed
4x6 cedar rafter tails. Noticed a couple of the ends have holes; worst looks almost like a couple of 1" diam. holes drilled 3"-4" deep. When I cleaned them out, most of the loose material looked like dry wood powder, but surrounding wood seems solid. No sign of insects or mold. Recommendations what to use to fill the holes? Plan to use Olympic cleaner before staining. Fix holes before cleaning or after?
TIA
