The entire concept behind Glassskinz?? started with drawings of unique concepts of S650 Mustang Window Louvers! The offerings on the market were so boring. The same old design applied to new body styles since the 60's! Mustang Rear Window Louvers were in desperate need of a makeover! This led to our first design for the Mustang Window Louvers with our Tekno 1 open port design, a first of its kind. Two open ports, left and right with a center waterfall,  allowed complete visibility with no obstruction. The center waterfall is real low profile unlike current designs on the market that looks plain mean!  It too was designed to ensure no rear view obstruction. We met a lot of push back from Mustang Window Louvers lovers at first but then it caught on as we featured this first design at SEMA in 2016.  Following we created 3 more designs and have a couple more waiting in the wings for introduction. This Glassskinz?? design Mustang Rear Window Louver is so unique we received Patent D825,419S on it as a rear mustang window valance not just a louver!
