If you have researched DIY ceramic coatings, you have run into CQuartz UK 3.0. It is CarPro's flagship prosumer coating and one of the most recognized names in the category — the coating enthusiasts compare everything else against. We stock the full CarPro line and use it in our own coating work; here is what CQuartz UK 3.0 actually is, how it performs, how to apply it, and where it sits against the rest of CarPro's coating lineup.
Quick Answer
CQuartz UK 3.0 is CarPro's flagship DIY ceramic coating — a 70% SiO₂ formula at 99.9% purity that bonds to your clear coat for 18–24 months of self-cleaning, hydrophobic protection and deep gloss. The 30ml kit ($69.99) ships with Reload 2.0 for maintenance, and a confident DIYer can apply it at home with proper prep.
What Makes CQuartz UK 3.0 Special?
CQuartz UK 3.0 is formulated with 70% SiO₂ at 99.9% purity — that high silica load is what gives it its hardness, gloss, and hydrophobic performance. It bonds permanently to your vehicle's clear coat to create an ultra-slick, self-cleaning surface with extreme water beading and sheeting, superior UV protection, and chemical resistance. The "UK" lineage is the tell: it was engineered specifically for climates with frequent rain and harsh conditions, which is exactly why it is such a strong fit for Florida's downpours and sun.
The self-cleaning effect is the headline benefit. On a coated car, rain sheets off and carries dirt with it instead of drying into spots, so the car stays cleaner between washes and the washes you do are faster and safer. Over a coating's life that means less contact with the paint — and fewer chances to instill swirl marks.

CarPro makes several coatings, and "which CQuartz" is the most common question. Here is where UK 3.0 sits:
| Coating | Who it's for | Price |
|---|---|---|
| CQuartz UK 3.0 | Flagship DIY pick — rain/harsh climates, best all-around | $69.99 |
| CQuartz Lite 2.0 | Beginners — forgiving, extended working time | $54.99 |
| CQuartz SiC | Silicon-carbide, installer-grade max hardness | $63.99 |
| CQuartz Gliss 2.0 | Slickest top coat — layer over UK for extra slickness | $45.99 |
| DQuartz GO | Nano-diamond, highest-end hardness/scratch resistance | $71.99 |
For most people coating their own car, UK 3.0 is the right pick — it is the proven flagship. Choose Lite 2.0 if it is your first coating and you want a forgiving application, or add Gliss 2.0 on top of UK for an even slicker, self-cleaning finish. Still deciding between brands?

Before You Coat
Prep is non-negotiable — a coating only bonds to a perfectly clean surface. Wash with CarPro Reset, decontaminate iron with CarPro IronX (see our IronX review), then wipe every panel with CarPro Eraser to strip polishing oils so the coating can bond. Skip these and the coating will not last.
How to Apply CQuartz UK 3.0
Prep the surface. Wash, clay/iron-decontaminate, correct any defects, then wipe down with CarPro Eraser. The paint must be perfectly clean and oil-free.
Work in the shade, panel by panel. Apply 2–3 drops of CQuartz UK 3.0 to the suede applicator and spread in a crosshatch over a small section. Never coat in direct sun.
Let it flash, then level. Wait for the coating to "rainbow" / flash (typically 1–5 minutes depending on temperature and humidity), then buff off with a clean plush microfiber, flipping to a fresh side often.
Cure it. Keep the car dry and out of rain for at least 12 hours (24 is safer); avoid washing for ~7 days while it fully cures.
Maintenance — Included in the Kit
CARPRO Reload 2.0 — $64.99 (1L)
The SiO₂ spray sealant that refreshes the coating's hydrophobics and gloss. Apply every 2–3 months to get the full durability out of UK 3.0 — and it is bundled in the kit.
Shop NowPro Tip
To hit the full 18–24 month durability, top the coating with Reload 2.0 every 2–3 months and wash only with a pH-neutral, coating-safe shampoo like Reset. A coating is a maintenance relationship, not a one-time spray.

Frequently Asked Questions
How long does CQuartz UK 3.0 last?
With proper prep and maintenance, CQuartz UK 3.0 delivers 18–24 months of real-world durability per CarPro's official spec. Top it with Reload 2.0 every 2–3 months and wash with a coating-safe shampoo to reach the upper end.
How long does CQuartz UK 3.0 take to cure?
It flashes and is buffed within minutes per panel, but keep the car dry and out of rain for at least 12 hours (24 is safer), and avoid washing for about 7 days while it fully cures and hardens.
Can I apply CQuartz UK 3.0 myself?
Yes — it is a prosumer coating designed for confident DIYers. The application itself is straightforward; the make-or-break is prep. Decontaminate and wipe down with Eraser first, work in the shade, and buff each panel before the coating cures hard.
Does the kit come with everything I need?
The 30ml kit coats one vehicle and ships with Reload 2.0 plus the application materials. You will also want your prep products (Reset, IronX, Eraser) and a stack of clean plush microfiber towels.
CQuartz UK 3.0 vs DQuartz — what's the difference?
UK 3.0 is the flagship SiO₂ DIY coating and the best all-around pick for most people. DQuartz GO adds nano-diamond particles for even higher hardness and scratch resistance at the top of the range — overkill for most owners, but the choice if maximum durability is the goal.
Does CQuartz UK 3.0 protect against UV and water spots?
Yes — it provides strong UV protection to slow paint fading and oxidation, and its hydrophobic, self-cleaning surface helps water sheet off before it can dry into spots. In hard-water areas, still dry the car promptly and consider a periodic Descale wash to keep minerals off the coating.
