Blair's Texas Window
Tinting and more
Lines and Bubbled Tint?
Will my rear defroster cause my
window film to bubble?
A lot of people see cars driving down the road with just their rear window bubbled. This
is not due to the rear defroster because if you think about it, it gets much hotter
sitting in the sun in the summer than when you use it when the window gets fogged. In
fact, window film helps defrosters work faster by distributing the mild heat across the
glass a little quicker. The bubbled cars you see are usually cars that the window film is
at the end of it's life span. Generally back windows are the first to wear out because
they take more of a direct hit from the sun (angled more towards the sky) than the sides
do. The sides tend to follow the back window wearing out by about 1 year (or so).
window films out there will eventually wear out (like tires, shocks, brakes, etc...) .
You're better off by the film taking all the sun's abuse and wearing out than your
upholstery (less money spent on repairs) This is where the quality comes into play. Better
films last longer than cheaper films do. If you have bubbled film needing to
be removed and re-tinted and are concerned about removing it off your
defroster lines then click the "Next" button below to go to that topic.
