A freshly washed car looks sharp for a day, then dust, rain and road film settle back onto the paint. Wax helps for a while, but a sealant is the layer that keeps water beading and dirt sliding off between washes. The best automotive paint sealant goes on fast, beads water hard and holds up for months, not days. This guide compares spray sealants for that job, from a rinse-off silica formula to a ceramic spray.

How the points were given
Each sealant is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. A spec the listing does not publish scores nothing.

Buying guide: best automotive paint sealant
Spray and buff, or spray and rinse
CARPRO is the only rinse-off pick: spray on and rinse off, with no rubbing or buffing. CERAKOTE, P&S and Flitz are spray-and-buff: CERAKOTE says spray a light coat and lightly buff, P&S says spray on wet or dry surfaces and buff off with a microfiber towel, and Flitz says spray onto a clean, dry surface and buff with a microfiber cloth. 3D Bead It Up states no application steps beyond acting as a top coat sealant.
How long it lasts
CARPRO states durable 3 months. Flitz states up to a full year when combined with the metal polish paste, and a second coat after 48 hours for ultimate durability. CERAKOTE, P&S and 3D state no durability figure, so their listings give no number to compare.
Ceramic and silica
Four of the five picks name ceramic or silica: CERAKOTE is a ceramic paint sealant, 3D uses SiO2, Flitz uses nano-ceramic technology, and CARPRO is a silica sealant. P&S names no ceramic or silica content, only UV filters and stabilizers.
Where else it goes
P&S is safe on paint, rubber, plastic, metal, glass and more. CARPRO protects body panels plus calipers, undercarriage, wheel wells, door jambs and seals. Flitz is safe on metals, fiberglass, clear coats, plastics, granite and glass. CERAKOTE and 3D name paint only.
Size and value
The picks run from 8 oz for Flitz to 1 gallon for 3D Bead It Up, with P&S at 16 oz, CERAKOTE at 32 oz and CARPRO at a liter (34 oz). A gallon suits frequent use across many washes; the smaller bottles suit occasional use. No pick states a coverage figure, so buy for the size of the job you have.
Keep electric pressure washers on a GFCI outlet, never point the wand at people or pets, wear eye protection with polishers and chemicals, and read the label before mixing any cleaning products. Read our Safety Disclaimer.
