Actually JohnM17 BCB took the original first cuts of the rails and stored them on top of the building for five (5) years to check the weathering. They actually forgot about the rails for a while, then recalled them being there in a conversation over the weathering. Those parts actually were out for the full term of five years in 100 degree sunshine, sub zero weather, hail, rain, the Big Ice Storm and all. You may recall a picture being posted on this site of one of the cut outs. They pulled the cuts down and they removed the junk from no maintenance with soap and water. Then they checked the parts for damage. They actual acrylic rails were pristine for their age. They did a lot of research early on in the spectrum and they found that silicone was tedious on the acrylic rails. There were a lot of products that in 2005 were used for the install that were taboo on the life cycle. After early 2005 Model Year (2004) they ended anything getting close to the rails other than soap and water or petroleum jelly. Which is those who tour the factory, or in production images, will now notice lots of small Windex spray bottles labeled water. We found that image and linked it up here. The actual cause of the issues were determined to be chemical related. Who knows what or how, though it is chemical related on the troubles.
