Nice basic info.

-Ceramic and glass coat as sacrificial layer against scratches. Since it is harder than the top coat of original paint job.
- Maintains gloss over a longer period of time, no waxing needed (they say from what was applied to my car)
- increase hydrophobic property ( I still opted for addl layer -Exo v3)
- will last 5 years as they claim ( although I doubt it) but even if it last for only 3yrs masaya nko.
-I would not appreciate the P20k addl cost for pearl white if not coated.

*** ask first if the coat ,glass or ceramic they will apply needs a "periodic maintenance". Deal breaker yan to many..

Cheers😊
