We built a a log home 5 years ago in NE Tennessee. The contractor ran out of money at end of project and went extremely cheap on stain. 2 years ago we had cabin blasted down to bare wood and put on Permachink with a ”reputable” contractor. Now some of the areas getting direct sun have faded and pealed off logs showing bare wood. 95% of house still looks great. Old contractor to ill to work and has retired. New contractor wants to go to bare wood again!!!! Can’t the faded areas be worked and
