Quick little story about Sunscape 

I was called out to a house that I installed Sunscape Designer Grey film on back in 2004. They had a group of windows that were tinted. These windows face due West and take the full brunt of the sun every day. One of the panes got damaged and had to be replaced.  Very pleased to report that a new piece of film made in 2016 matched up 100% with the old film.
