i have 1/2 log siding that the 1st 3 rows were getting black spots so i pressure washed them and restained with penofin red label. 1 year later they are almost all black, the siding above looks great, do i strip it? and if so do i do the whole house or just the effected areas? thank you.

You more than likely didn’t allow the wood to dry enough before staining and trapped the moisture in the siding which causes the black mold. Also, I believe that Penofin is Linseed oil based which promotes mold growth. I would say strip the dark lower area’s by sanding then re-stain to match. Dry logs are happy logs. Put the power washer away.
