People often say that the election of the do not choose expensive , automotive film is the same , admittedly a sub-price goods, but not necessarily expensive is suitable for them. "Or according to demand ," the natural have your truth , more than a thousand from the price to more than one hundred and eighty thousand , and in terms of safety and 180,000 membrane is bulletproof , but may in insulation effect, not like a thousand films. When it comes to cars membrane function , first of all have a good car film has a certain security, including the security of clarity, but security is not absolute.
       According Kero   Throttle Body  noted that in the current common market, product categories , in fact, nothing more than the following categories. The first is the basic insulation series, the main function is insulation, safety index to none. Followed by a series of safe, high thermal insulation , thermal insulation and safety are good. Privacy high heat longer series, although far from safety index , but privacy has been a guarantee - without worrying about the clarity of the question here , inside and outside look inside to see outside is completely different . Finally chameleon high thermal insulation series, looks very compelling.
Currently there is not a direct and effective way , allowing riders themselves to identify the pros and cons of solar film quality . For the more common metal film can be "a look at two Wen three touch" , first look at the film 's color is uniform , is clear ; then smell the smell is pungent ; Finally, you can shake the film , listen to whether metallic crisp sound. However, a method like this , can not be used as an absolute standard .

The industry 's products are not very intuitive, need some professional equipment to detect . Although they are often dealing with film , but they can not accurately determine their true and false and bad films . Because solar film is not a consumer brand, but the channel brand . For consumers, the only way is to choose a well-known brand of international certification .

Before the film , consumers can first on the brand's official website to see film of the stores or 4S shop is not authorized the construction of the brand film center , the official online store can be found is true ; see is not real film ( currently on the market there are parallel, may be smuggled or tax evasion , the quality with the mainstream there are subtle differences , but no warranty or viscose film preservation bad ) , in the real shops have officially licensed premise, also can provide consumers with electronic warranty card, which combines two conditions , we can ensure that film is genuine. Such as 3M film , ordinary film can be 5-year warranty , the top film warranty for 8 years.

Authentic brand film electronic warranty card is free for consumers , the owner may apply to foil warranty card , the warranty period counting from the day of application . Bubbles during the warranty period , faded, unglued, stick is not strong and other issues, consumers rely on the warranty card to store electronic request a free replacement, consumers' interests can be protected .

Remind owners , before the film , try not to put on the glass , such as annual and other types of signs, car window regulator should ensure the proper functioning , such as problem , you should first repair and then foil. Before the film should also ensure that the integrity of the vehicle glass breakage , glass and do not spray polishes , anti-fogging agent a chemical sprays .

Kero  Throttle Body  recommended that owners , foil 3 days Do not lift windows or water washing , because just posted solar film does not completely fit with the glass , prone to shifting and seepage. Identify problems, should be sent back to the original film shop inspection . Never use a sharp object poke owners foil edge , once into the air and dust, foil quality will be compromised. Foil week, electrically heated glass defogging try not to use , in order to avoid foaming film is heated to high temperatures . If bubbles appear , you should promptly contact with the store , not themselves. Try to make the film to avoid contact with ammonia or alcohol content of the solution, so as not to affect the effective membrane function .
