The dealership where I purchased my vehicle has sold me the darkest legal tint. What does this mean?
In Australia (and many other countries) there are state laws that state the minimum amount of (filtered) light that must enter through glass. This is referred to as VLT or visual light transmittance. The front windows must be no darker that 35% and for the rear windows, in most states, this can be as dark as 20% VLT. Most coloured window films are manufactured to produce a (nett) result of 35%. However, films can appear darker when the film has been made using a dark pigment during the colouration process. This produces films which appear darker when compared to others. Many dealerships refer to the darker coloured films as their darkest legal film.
