DIY window tinting kits are available for consumers, but many still choose to use tinting services for the tint job. Tinting specialists are more up to date with the existing tint law and darkest legal tint. The window tint film regulation may depend on the local government, so you better find out what is the legal tint in your territory.
Factory tint. The factory-tinted glass contains dyes and pigments that are mixed into the glass itself during manufacturing. It has pigments and dyes that are added to the glass during the manufacturing process. It darkens the glass and reduces the amount of visible light that passes through the car’s window. This type of tint is also known as privacy glass and is considered an extra-cost option. To stick to the law, these privacy glass has a Visible Light Transmission (VLT) of between 15%to 26%.
Aftermarket tint. This type of glass tint is a polyester film comprised of multiple layers. It includes an adhesive coating, layers containing metal particles, dyes and pigments, and a final layer that makes it scratch-resistant. After-market window tinting has benefits that factory tint does not provide.
While DIY tinting is something that you can do, it requires extra care to get it installed right. Poor tint job will likely create bubbles in the surface or just ruin the film altogether. It may cost you more for a new tint kit or call an installer in the end.
In Australia, most territories do not allow tint on the windscreen and allow 35%, 20% or 15% on the front windows and rear windows. They do allow a 10% visor strip of any colour on the windscreen though. There are tinting requirements and the proper installation of window films, that is why your local window tinting companies can get the tint job done right.
