Gyeon is one of the most respected names in ceramic coatings — a Korean brand built around a single idea: layered, dedicated products that each do one job extremely well. That depth is also what makes the lineup confusing. Is CanCoat the same as a real coating? Do you need Mohs or Syncro? What's the difference between Bathe, Cure, and Preserve? This guide walks the full Gyeon system the way you'd actually use it — wash, decontaminate, coat, maintain, and protect the interior — and tells you which product fits where. Everything here is genuine Gyeon, stocked and shipped from our Orlando warehouse; browse it all in the Gyeon collection.
Quick Answer
Most people want one of two coatings: Q² CanCoat EVO for an easy, wipe-on SiO₂ ceramic that lasts about a year, or Q² Mohs EVO for the flagship 9H, multi-year professional coating. Wash with Q²M Bathe, decontaminate with Q²M Iron Redefined, and keep any coating beading with Q²M Preserve.
Step 1 — Wash: Q²M Bathe
Every Gyeon routine starts with a coating-safe wash. Q²M Bathe is a pH-neutral premium shampoo built specifically for coated cars — it lifts grime without stripping ceramic coatings, sealants, or wax, and its 1:500 dilution makes one bottle wash dozens of cars. If you want the cheapest-per-wash option, the concentrated Q²M ECO Wash does the same job. New to coating-safe shampoos? Our car wash soap guide explains why pH-neutral matters.
Wash · pH-Neutral
Gyeon Q²M Bathe 500ml — $15.99
pH-neutral premium shampoo for ceramic-coated vehicles. Slick, high-foaming, and concentrated 1:500 — it won't strip coatings, sealants, or wax.
Shop NowStep 2 — Decontaminate: Q²M Iron Redefined
Washing removes loose dirt; it can't touch the embedded iron and brake dust bonded into your paint and wheels. Q²M Iron Redefined is Gyeon's pH-neutral iron remover — it visibly bleeds purple as it dissolves ferrous particles, yet stays gentle on coated surfaces and modern wheel finishes (about 150 ml covers a vehicle). For a deeper look at how iron removers work and how Gyeon stacks up against the category, see our CarPro IronX review and the full iron decon shootout. Before a coating you'll also want Q²M Clay Lube for mechanical claying and, if you're recoating, Q²M Total Remover to strip old coatings, sealants, and wax.
Decontamination · Color-Change
Gyeon Q²M Iron Redefined — $19.99
pH-neutral iron and fallout remover that bleeds purple as it dissolves brake dust and rail fallout — safe on ceramic-coated paint and wheels.
Shop NowStep 3 — Coat (Easy): Q² CanCoat EVO
This is where Gyeon gets famous. Q² CanCoat EVO is the easiest way to get a genuine SiO₂ ceramic coating without a full professional install — wipe it on, buff it off, and you've got up to 12 months of hard, hydrophobic, candy-gloss protection on paint, glass, wheels, and trim. No machine polishing required to apply. It's the perfect step up from a spray sealant, and our spray vs professional coating explainer covers exactly where it fits.
Ceramic Coating · Easy DIY
Gyeon Q² CanCoat EVO — $62.99
Genuine SiO₂ spray ceramic coating — wipe on, buff off, up to 12 months of protection. The easiest real ceramic coating to apply at home.
Shop NowStep 3 — Coat (Flagship): Q² Mohs EVO
When you want the real thing, Q² Mohs EVO is Gyeon's flagship: a 9H-rated professional ceramic coating with a deep mirror gloss, chemical resistance from pH 2 to 11, and up to 36 months from one layer (48 from two). It's a prep-heavy install — wash, decontaminate, machine polish, then wipe down with Q²M Prep so the coating bonds to bare clear coat. Need maximum life? Q² Syncro EVO layers a Mohs base under a Skin EVO topcoat for up to 50 months. For how Gyeon compares to other premium coatings, see our ceramic coatings comparison and CQuartz vs Gyeon breakdown.
Ceramic Coating · Flagship 9H
Gyeon Q² Mohs EVO 30ml — $76.99
Flagship 9H professional ceramic coating — deep mirror gloss, pH 2–11 chemical resistance, up to 36 months from one layer. Ships with applicator and Cure.

Step 4 — Maintain: Q²M Preserve
A coating isn't set-and-forget — it beads less as it ages. Q²M Preserve is a spray-and-wipe booster that restores hydrophobic performance between annual services and extends the practical life of any Q² coating. After a coating install, Q²M Cure Redefined levels the fresh film, and the Q²M Silk Dryer EVO (a plush 530 GSM towel — one of the best drying towels you can buy) dries coated paint scratch-free.
Maintenance · Coating Booster
Gyeon Q²M Preserve 250ml — $16.99
Maintenance booster that restores beading and gloss on coated cars between services — spray on after washing, wipe off, no buffing.
Shop NowStep 5 — Protect the Interior: Q² LeatherCoat Redefined
Gyeon's protection philosophy extends inside. Q² LeatherCoat Redefined is an SiO₂ ceramic coating for leather — clean the seats with Q²M Leather Cleaner Natural first, then lay down an invisible hydrophobic barrier that guards against UV fading, dye transfer, and spills while keeping a natural satin finish. For cloth interiors, Q²M Fabric Cleaner handles upholstery and carpets, and Q²M Odor Remover neutralizes smells at the molecular level.
Interior · Leather Protection
Gyeon Q² LeatherCoat Redefined — $12.99
SiO₂ ceramic coating for automotive leather — guards against UV, dye transfer, and spills while keeping a natural satin look and feel.
Shop NowFrequently Asked Questions
Is Gyeon CanCoat a real ceramic coating?
Yes. CanCoat EVO is a genuine SiO₂ ceramic coating — far more durable than a wax or sealant, with up to 12 months of protection from a single application. The difference from a flagship coating like Mohs EVO is hardness and lifespan, not whether it's "real" ceramic. It's simply applied by hand instead of requiring machine polishing and prep.
What's the difference between Mohs EVO and Syncro EVO?
Mohs EVO is a single flagship coating rated 9H, lasting up to 36 months from one layer (48 from two). Syncro EVO is a two-part system that pairs a Mohs EVO base with a Skin EVO topcoat for a thicker film and up to 50 months of durability — the longest in Gyeon's catalog. Choose Mohs for maximum hardness in one product; choose Syncro for maximum lifespan.
How do you apply a Gyeon ceramic coating?
For flagship coatings: wash, decontaminate, machine polish to remove defects, then wipe every panel with Q²M Prep to strip oils. Apply the coating in straight overlapping lines one section at a time, wait 60–180 seconds until it "sweats," then buff off with two plush microfiber towels. Keep the car dry and out of sun for 12 hours; full cure is about 7 days. CanCoat EVO skips the polishing step — just wipe on and buff off a clean, decontaminated surface.
Is Gyeon Q²M Bathe safe on ceramic coatings?
Yes — Bathe is pH-neutral and engineered specifically for coated vehicles. It lifts dirt without stripping ceramic coatings, sealants, or wax, which is exactly what you want to preserve a coating's beading and lifespan. Pair it with Q²M Preserve every few washes to keep hydrophobics topped up.
