Window tinting actually helps to insulate the window and helps the defroster clear the glass of frost and fog quicker.
You must have had a metalized film applied to your windows. Metalized film has a much slower drying time. Under normal drying conditions, such as hot summer days, it will take 1 - 2 weeks; wintertime the drying time usually takes 30 days. Also, drying time depends on how much sun exposure the windows receive during the day. The more sun, the faster the drying.
V rays from the sun that are responsible for damaging your cars interior and excessive heat build-up are usually the cause of bubbles forming in the window tint. The bubbles are a result of a failure in the adhesive system. Protect yourself from this potential problem by purchasing a major brand name window tint material. The major window tint manufacturers, in their high performance and metal window tints, have a high temperature adhesive system and 99% of UV protection capabilities, which along with the metalizing technology, allows them to give a manufacture backed guarantee against bubbling of window tinting. These films are available from most reputable dealers.
The black dots, or matrix patters, as well as the lines at the top of some windows are made of a Teflon type of material that is applied at the factory. Purely cosmetic, they hide trim lines and edges on different styles of autos. The thickness of these Teflon type areas make them a nightmare when applying window tint. Window tint is designed to adhere directly to the glass. The black lines across the top of some windows can prevent window tint from sticking and cannot be covered. When black dots are encountered, the window tint sticks to the slightly raised dot. This can give, depending on the thickness of the material, a lighter or different look in the area of the black matrix dots. This poses no risk of peeling. In some cases, the dot pattern or lines usually put at the top of some windows are so thick that it makes it impossible for the tint to stick at all.
The answer is yes. Unfortunately, most tint shops are not work areas that are sealed in a vacuum (vacuum-sealed: a space relatively empty of matter) so one will have tiny air particles caught onto the film. However, as the film cures, usually after a hot summer, it will tighten up around these sports and they will become even smaller and less noticeable.
We recommend a non-ammonia cleaner and a soft cloth, such as a T-shirt. Vinegar and water (1 part vinegar to 10 parts water), or Windex with vinegar available at any store. Be sure to read the label that it does not contain ammonia. It you use a professional window cleaner let them know which windows are tinted.
One question asked thousands of times about durability is, "Will my kids tear it up?" We are glad to report this is not a problem. Pets are also a concern but damage is usually confined to smudges that just need to be cleaned. The hard scratch-resistant coating found on quality window tint products do an excellent job protecting window tint from everyday use as well as kids and pets. A word of caution is to remember window tinting is installed on the inside of the glass and is usually coated with a high quality scratch resistant layer for protection. However, the key word is **resistant**. Take care when loading and unloading objects with sharp or hard edges, boxes, sporting equipment, etc. It is possible to tear even the best window tinting material with a sharp or hard object hitting against the tint. Glass without tinting, or with factory window tint; can be damaged in this fashion also. Remember if you accidentally damage a window, the cost of replacing the window tinting material on one window is not that expensive.
