Is this for skin or for cars?

For cars. The formula is silicon dioxide, polysiloxane and silazane, a spray sealant for painted surfaces. Do not apply it to skin.

Wash and dry the car, spray evenly onto the paint, let it form a film, then wipe off the excess with a clean microfiber towel. Work one panel at a time.

How long does the protection last?

Spray silica sealants typically last weeks to a few months, less with frequent washing or harsh weather. Reapply when water stops beading.

Does it replace a ceramic coating?

No. A professional ceramic coating cures harder and lasts years. This is a maintenance layer for gloss and water repellency.

Can I use it on glass and trim?

Yes, it beads water on glass and darkens plastic trim. Keep it off rubber seals and matte surfaces if you want to avoid a patchy look.

Will it remove scratches or oxidation?

No. It adds a protective layer over the paint. Swirls, scratches and dull oxidation need polishing first.

Our take on the Crystal Plating Agent

A spray-on silica and siloxane coating sold for car paint, not skin, despite its category listing. It forms a thin protective film that beads water and slows UV fading. It suits drivers who want a quick DIY layer of gloss and water repellency between waxes or ceramic coats. It is not a substitute for a proper ceramic coating: the film is thin and short-lived, and reviewers of similar spray sealants report uneven results on neglected or swirled paint.
