DURING THE OFF SEASON WERE PLANING TO RESEAL THE WINDOWS IN OUR C30. NOW THERE ARE ALL KINDS OF INFO ABOUT HOW TO DO THIS ,BUT WE HAVE NOTICED THAT ONE PIECE OF GLASS IS NOT TINTED. AFTER LOOKING A LITTLE CLOSER WEVE DISCOVERED THE TINT SEEMS TO BE INSIDE OF THE GLASS ON THE OTHERS. IS THIS FACTORY OR IS THIS AN ADD ON? HAS ANYONE SEEN THIS BEFORE? SHOULD I JUST TRY TO MATCH THE TINT? HELP!
