Source:eBay DIY Window TintsA DIY window tint job isn't what you would call a casual undertaking. If you're going to do this, you have to be willing to submit to a process that can take time and it can take a great deal of patience.
The good thing here is that a window tint job is done the same way, no matter that what kind of window you working on – be it your car or your house. The one thing you do want to be careful of when you tint your car windows though is that every state has strict laws against how dark they will allow them. Apparently, it's a public security threat when the police can't look in into a car through the Windows.
A good window tint job always starts with a spectacular window cleaning. They need to be squeaky clean – not a single stray piece of lint or anything anywhere. When you put the film on, any dirt that's on the window is going to be trapped there forever. Lint isn't going to let the film stick on properly, and it isn't going to look good.
Thankfully, it isn't that hard to do a thorough cleaning. You just need a spray bottle filled with soapy water, plain, distilled water, and a lint-free towel.
If you're not so lucky as to have precut film available, you'll have no option but to take the plunge and cut the film yourself. It isn't a good idea though to just use plain scissors or anything. You need exactly the right kind of cutting implement. For window film, this is usually an X-Acti knife.
You should cut something that seems the approximate size, tape it over the window in question, and then trim the excess with your knife.
The tricky part of course is when you need actually apply the film to the window. The adhesive tends to be a quick drying material. You need to work quickly. It takes a quick unpracticed hand to be able to spray a window with soapy water, to peel the backing off a sheet of window tint film, and then to apply the film.
Once the film is applied, you need to use a squeegee to quickly go over every inch repeatedly to work any air bubbles out before anything should dry.
