We have bought a 20 year old log cabin that has been painted gray. We would like to restore it back to a nature color, and unsure of the best way to do so. We have been told to corn blast it, however that is a little out of our budget. We were told not to powerwash it, however, I see a lot of people here on this site have done so. I have also been told to use a solid Cabot paint to just go over the alreay gray paint. Any ideas that you might have would be great. Thanks for your help.
