Georgia
Lake Chatuge sets the terms here. Houses ringing the shoreline and the coves near Sunnyside Estates sit in steady humidity, and the water throws afternoon sun back onto siding already taking direct UV. Towns County is also the highest, coldest corner of Georgia, with Brasstown Bald just up the road, so those same walls swing through freeze and thaw from December into March. Cedar, log and older painted lap siding show it plainly: green and black growth on the shaded elevations, chalking on the exposed ones, and coatings letting go at the seams. A 25-year warranty that transfers to the next owner is a serious promise in that climate, which is why the specification behind it matters. Rhino Shield is a ceramic coating applied at no less than 10 to 12 mils, close to ten times what ordinary house paint leaves. It bonds tight and stays flexible, so seams do not open and the film does not flake, and the repaint a mountain house needs every three to five years stops coming due.
