Coverage
≈ 350 sq ft per 16 oz bottle
A 24 ft boat (~528 sq ft) takes about 2 bottles of Aqua Armor per coat.
Rough estimate from typical topside area — real use varies with prep, surface, and conditions.
Start with a clean, dry surface — a fresh Sea Scrub wash or a Deck Hand wipe-down is the prep that makes the coating last.
Shake the bottle well, then spray Aqua Armor evenly onto the surface in manageable sections.
Buff with a clean, dry microfiber cloth until the surface is smooth and glossy.
Allow 24 hours to cure for maximum protection, and keep water off the surface for at least the first 2 hours.
SiO₂ (silica) ceramic polymer blend. Durability figures reflect in-house saltwater testing; real-world results vary with surface prep, storage, and conditions.
An SiO₂ ceramic spray that bonds a mirror-gloss, hydrophobic shield to your boat — repelling water, salt, and UV for up to 6 months. The whole job is two steps: spray on, buff off.
Aqua Armor cures on prepped gelcoat into a hard SiO₂ film — water sheets off, and grime has nothing to grab.
Water beads up and sheets off — dirt rinses away with it.
A hard, glossy shield against UV, salt and oxidation.
Bonds to the surface instead of rinsing off with the next wash.
Decontaminated and corrected so the coating keys in.
Slide the handle to compare the same hull before and after one application.
A slick, hydrophobic layer makes rain and spray sheet right off — so the shine you put in stays put between washes.

“The morning dew test”
You know it's working when the dew sits on the bow in little round beads instead of a wet sheet. Sprayed it on after a wash, buffed it off, that was it. Bird bombs rinse off with the dock hose now instead of needing a scrub. At fifty bucks a bottle I was skeptical. Not anymore.
“Neighbor asked what wax I use”
Black gelcoat looks wet at the dock now. Did the whole 21 footer in under half an hour, no machine, just spray and buff like the bottle says. The guy in the next slip asked what wax I used and I told him elbow grease. Sorry Dave.
“Chalky hull looks deep again”
Hull came out of winter storage chalky and dull. Washed it, did two thin coats before we splashed in April, and the gelcoat actually has depth again. Two months in the salt so far and water's still sheeting off. Still way under the 6 months the bottle claims so ask me in the fall.
“Sprinklers vs Aqua Armor”
The dock sprinklers hit my boat every single morning and the hard-water spots used to bake on by noon. Since coating it they wipe off with a damp towel. I bought it for the gloss but honestly the spot thing is why it's staying in the dock box.
“Use way less than you think”
Did the hull in the driveway before we splashed for the season and my first panel streaked because I soaked it like a spray wax. It is not a spray wax. A couple light mists, buff, flip the towel — the rest came out like glass. Mostly user error but I'd put USE LESS on the label in bigger letters.
“Works, but the bottle doesn't go far on 30 feet”
No complaints about how it performs. Beads hard, looks glossy, easy to put on. My issue is I have 30 feet of hull plus the cockpit and I used most of the 16 oz bottle in one application. For $50 I want it to stretch further. If they sold a bigger size I'd bump this to 5 stars. Will update on how long it lasts.
“ok this stuff is legit”
water flies off the hull at 30mph now lol
“Paste wax husband has been converted”
My husband has used the same paste wax since the Clinton administration and treats anything in a spray bottle as a personal insult. Then our slip neighbor did his transom with this in front of us and the water beaded right up, and Doug went real quiet. We did our hull Memorial Day weekend, me spraying, him buffing, the usual arguing. Two weeks of Lake Michigan weather later the water still runs right off. He maintains the paste wax was better. He also told me to get two more bottles, so make of that what you will.
Up to 6 months of protection per application based on our saltwater testing. Boats kept covered or on a trailer tend to see the longer end; heavy daily saltwater use sits closer to 3–4 months. A quick re-coat tops it right back up.
No. Aqua Armor is a true spray-on, wipe-off ceramic — spray evenly, then buff with a clean, dry microfiber until smooth and glossy. No machines, compounds, or cure lamps.
Yes. Use it as a standalone coating or layer it over existing wax/sealant for an extra layer of protection. For maximum durability, apply to a freshly washed, dry surface.
Keep the surface dry for at least 2 hours while it sets, and allow a full 24 hours to cure for maximum protection. Avoid non-skid decks, where you want grip, not slickness.
