How long does Meguiar's Ultimate Ceramic Coating last?

Meguiar's rates water-beading protection at up to one year. Real-world life depends on prep, weather and washing, and most owners see it fade gradually rather than stop at once.

Can I use it on glass, wheels and plastic trim?

It is made for painted surfaces, plastic trim, wheels, decals and PPF. Glass is not its main job; use a dedicated glass coating or repellent there.

Wash and decontaminate the surface, spray onto a panel or applicator towel, spread evenly, then buff off the residue with the second microfiber towel. Keep it dry during the initial cure.

How many cars does one bottle cover?

Meguiar's says one bottle treats at least four vehicles. A single car uses only a small amount, so most of the bottle lasts through several applications.

Is it as durable as a professional ceramic coating?

No. Pro coatings applied in a shop typically last several years. This spray product is easier and safer for DIY use but gives roughly a year of protection.
