How to attach high-performance original film

Collect as many records as possible. The brand of solar film has been chosen.

1 brand origin: where is the production factory (Google search English website is highly reliable) and make records.

Verification: See if there are any selected brands from International Window Film Association, American Skin Cancer Foundation and International Association of Industrial Metallization and Coating Composites (with top technology manufacturers). I hope you won't be wiped out. At present, probably no more than five companies can pass this screening.

Choose a good brand before choosing a construction shop, except those who like DIY.

Go to official website to check the local authorized stores, and enter the store to choose the product model that suits you.

4. Record the factory number on the film, reel and packing box. These three figures can be used to bargain with the boss and to carry out construction, but they are not the same (it is more hateful to sell dog meat by hanging sheep's head).

5 ask for quality guarantee after construction. The verification information in official website specially reminds you to carefully check whether the volume number is consistent with your record. Pay, check the car, and then leave. Inconsistent! Haha-it's up to you whether he plays with you or not.

The original hard warranty card usually arrives in about a month, which is not the main thing (just remember to verify the information online)
