What about the federal solar film?

Hello, the problem of solar film and car film depends not only on the brand, but also on the skills of the film construction personnel. The effect of film pasting is the most important. After pasting, you can see if there is sand or air bubbles in it. If there is, it must be that the technology of the film construction personnel is not in place. Another point is that there are too many fake car films now, so it is not recommended to go to a small shop. Now choose the film to see what price you want, don't choose the low-grade one, the quality is poor, and the smell will be harmful to your health in a few months, so it will only be cheap and expensive. Ray-Ban, I don't think much of 3M, because most products on the market are fakes, which are really rare. Other brands say it's ok. If it's an ordinary mid-range car, just post a general brand. Johnson & Johnson, Federal Solar Film and Dragon Film are all good, and the price and quality are all ok. There are quite a few people who put up these brands.
