Paint Protection Film
Paint Protection Film (PPF) is a thermoplastic urethane film applied to painted surfaces of a new or used car in order to protect the paint from stone chips, bug splatters, and minor abrasions. OEM approved by virtually all car manufacturers. Commonly referred to as clear bra, clear film, clear paint film, PPF and other names. The primary function of clear bra is to prevent rock chips in paint, scuffs, many types of vandalism and other scenarios that result in superficial damage to car paint.
Paint protection film is mostly installed on the forward facing portions of automobiles but may also be installed on as much as a full body of a vehicle for the maximum paint protection.
Paint Sealant
Paint Sealant is a sealant that protects cars from ultraviolet rays and acid rain. Paint sealants protect cars' finishes, and can make cars shiny. There are synthetic sealants and carnauba waxes.
Salt may be a factor that many protective sealants do not defend against, and thus salt water may break down protective layers to get at the metal and corrode it.
Paint sealant works by filling into the pores and irregular surface of the body thereby creating a smooth finish on top. The way it helps is it denies a sticking surface to foreign substance and they come off the car easily without further damaging the car surface
