Hes talking about detailer sprays that neutralize static charge induced by waxing your car..
Cermaic coatings are proper coatings.. miles ahead of sealants.
Last a couple of YEARS not months. They are like an additional layrr of clear coat. Any imperfections will trapped under it forever. You need a perfect base to apply it.. you dont need to waf your car once you apply these.. it takes a little skill to apply them super thin, leveling off any high spots as you go..
This is what comes to my mind..
