How long does the protection last?

Meguiar's claims up to one year of water beading. Real-world life depends on prep, weather and washing habits, and many owners see strong beading for several months.

How many cars does the kit cover?

Meguiar's says at least four vehicles. A single car uses only a fraction of the bottle, so most buyers get several applications.

Do I need to prep the paint first?

Yes. The kit includes a prep spray that removes old wax and residue so the coating can bond. Applying over a dirty or waxed surface shortens durability.

Can I use it on glass and wheels?

Yes. The coating works on paint, glass, wheels and plastic trim. Keep it off unpainted rubber and textured plastics where it can leave a white residue.

How is it different from a spray wax?

A spray wax lasts weeks; this ceramic coating is claimed to last up to a year and beads water more strongly. It takes more prep and cure time than a quick wax.

What happens if it rains during curing?

Water during the cure window can hurt bonding and cause spots. Apply when the car can stay dry for the recommended cure period, ideally indoors or under cover.
