Paint protection films use by the military has continued to the present day and 3M now makes a wide variety of aerospace and military films. [3] With time, however, the automobile industry began to take note of the protective benefits of PPF and it was soon being employed by race car drivers despite the difficulty of working with the original films.
The term "cast" refers to the manufacturing process of this type of vinyl. Cast films are considered the industry premium. These films start in a liquid state with the ingredients blended together and then poured onto a casting sheet. The casting process produces a thin gauge film—usually 1- to 2-mil thick.
The film thickness is selected for level of protection desired and the dimensions of the glass pane. Manufacturers recommend 100 micrometer film (2 ply) for glass up to 3 mm (1/8 in) and 175 micrometer film for glass over 6 mm (1/4 in). These films can be applied for security applications, where a delay of forced entry is desired.

Doped metal oxides for use as transparent conducting layers in photovoltaic devices are typically grown on a glass substrate. This glass substrate, apart from providing a support that the oxide can grow on, has the additional benefit of blocking most infrared wavelengths greater than 2 μm for most silicates, and converting it to heat in the glass layer.
Workers who handle PFAS-containing products can also be exposed during their work, such as people who install PFAS-containing carpets and leather furniture with PFAS coatings, professional ski-waxers using PFAS-based waxes, and fire-fighters using PFAS-containing foam and wearing flame-resistant protective gear made with PFASs.
