A high-quality film should be at least 6.5 mils thick to provide adequate protection.

Clarity Is Key

One of the biggest advantages of using an invisible car paint protection film is that it is virtually invisible. This means that the clarity of the film is critical.

There are trial and error when installing the PPF to edges and corners here and there, a low initial bonding glue will help the install process much easier. But once it is installed properly the potency of the glue will ensure a tight bonding for years.
Another vital process is when removing the PPF when car owner wants to upgrade their drive or change to a new PPF, at this time, a high quality PPF should leave no glue on paint surface.  Long-term stability of controlled tack and cohesion to ensure no glue residue-The perfect match of glue and TPU film, can be pasted repeatedly, rework and stretch without leaving glue residue, ensuring the easiest modification and upgrade next time
