No, you can not combine the film in this way, you will lose the safety function. The safety film is come with special adhesive to strong hold on the glass. The first layer must be safety film.
Senario 1 :
Glass | (1) Solar Film | (2) Safety Film = No safety function
Senario 2 :
Glass | (1) Safety Film | (2) Solar Film = Got safety function.
By the way, safety film is not suitable to tint for front and rear windscreen. if you think your existing film is good, what you need to do is just change the all side windows to safety film, remain the front and rear windscreen film.
oh man, what a waste then..
next question, i think my existing tint is dark, around VLT : 55%.
i don't know if it's me or what..
i feel the weather is killing me lately..
my tint is just less than a year old..
i'm thinking of overlaying them with another, higher protection etc.
possible?
