Benefits of  Window Tinting

Window tinting blocks up to 99% of the UV rays. The car interior cools by 60%. It also can help protect from ultraviolet radiation and help protect your car’s interior from cracking or fading and looking worn-out. Another great benefit is the level of privacy, which can prevent someone who walks by to peer inside.

Car Window Tint Cost

In general, the cost may vary; for example, a basic tint for a sedan car using the classic film can cost less than $150 per vehicle. However, suppose you want a top-quality film such as ceramic window tint. In that case, it can cost up to $400 per vehicle. Of course, all depend on different factors (number of windows, type of tint, warranty). On the other hand, a cheaper option for professional tinting services is a DIY tint kit, which usually costs less than $100.
