I work as an engineer at Toyota during the day time... rest assure... no coatings are going on the in factory. That was either the Xzilon sales pitch or the saleman pitch to sell it...
The glass sealant for the windshield says on the package it protects against rock chips??? WHAT?
interestingly enough it's apparently possible for liquid glass coatings to reduce impact damage. tho i know nothing about xzilon. i know of a manufacturer that did lab impact testing with bbs with various iterations of a particular glass coating and there was a drastic reduction in damage with the coating vs. without. i can't remember the numbers but it was something like 9 out of 10 bbs damaged the glass without coating and 1 out of 10 on coated glass.
the glass is microscopically composed of jagged peaks and valleys. when something hits it, it catches those peaks, jars them and compromises the glass to varying degrees. when the glass is coated with the right stuff, the valleys of the jags are filled so everything is level with the peaks, thus, offering a microscopically smoother surface with less chance for damage and making the tall peaks more stable since they are insulated along with the neighboring peaks using the coating as a bridge.
