See above The Tuff Shed brochure I received when purchased reads "All trim boards will have been painted front, back, sides, top and bottom before installation on your building. This process makes it virtually impossible for moisture to penetrate the substrate." Unfortunately moisture has deteriorated the trim boards and lower 8 inches of the siding. The trim boards are rotten and the local Tuff Shed office will not repair it. Furthermore, the brochure reads, "All four edges of your siding are painted. This is very difficult to do after your building has been assembled." The inside of the siding has not been painted.
