Optimum Polymer Technologies was founded by Dr. David Ghodoussi, a chemist who invented Optimum No Rinse (ONR) in 2005, the original rinseless car wash concentrate that's still sold today, now on its sixth revision as ONR V6. That background in advanced polymer chemistry carried through into Optimum's ceramic coating work, where the company moved away from the SiO2 chemistry common across the category and built Opti-Coat Pro around silicon carbide instead.
What's the difference between Optimum and Opti-Coat? They're not separate companies, Opti-Coat is Optimum Polymer Technologies' professional ceramic coating brand, sitting alongside Optimum's wider range of washing, correction and maintenance products like ONR, Hyper Polish, Hyper Compound, Paint Prep and Power Clean. As a rule of thumb, products carrying the plain Optimum name are generally DIY-accessible, while products under the Opti-Coat Pro banner are the certified-installer-only ceramic coatings.
Silicon carbide is significantly harder and more chemically resistant than silicon dioxide, which is why Opti-Coat Pro can carry a 5 to 10 year warranty where most SiO2-based consumer ceramic coatings only claim 1 to 2 years. That durability gap, combined with a certified installer network trained specifically on the product, is a large part of why Opti-Coat became one of the more recognised names in automotive ceramic coating rather than just another bottle on a shelf.
Opti-Coat's reputation is built on Pro, Pro Plus and Pro3, the professional-install coatings, and those are the products most of the catalogue is built around. There's exactly one DIY ceramic coating in the range, Hyper Shine, alongside a handful of maintenance and specialty products anyone can buy.
Opti-Coat Pro, Pro Plus and Pro3 are professional-install coatings, sold only to certified installers and applied through Opti-Coat's certification process. If you're browsing as a regular customer and see "Professional login" instead of an Add to Cart button, that's why, it's not a stock issue. Apply to become a certified installer here.
Most ceramic coatings on the market, including the majority of consumer spray-bottle coatings, are built on SiO2 (silicon dioxide) chemistry. Opti-Coat Pro was one of the first coatings to use SiC (silicon carbide) instead, which is a harder, more chemically resistant material.
That's the reason for the warranty gap you'll see across the industry: SiO2-based consumer coatings typically carry 1 to 2 year durability claims, while Opti-Coat's SiC-based Pro range carries 5 to 10 year warranties, with Pro3 offering an optional lifetime warranty when maintained annually by a certified installer. Hyper Shine, the DIY option, uses a different formulation suited to self-application, with a 3+ year durability claim, still well ahead of typical consumer coatings.
| Chemistry | Hardness | Typical Warranty | Common Use |
|---|---|---|---|
| SiC (Silicon Carbide) | Harder, more scratch and chemical resistant | 5 to 10 years, optional lifetime with maintenance | Professional-install coatings: Opti-Coat Pro, Pro Plus, Pro3 |
| SiO2 (Silicon Dioxide) | Softer than SiC, still harder than wax or sealant | 1 to 3 years typically | Most consumer spray and DIY coatings, including Hyper Shine and Ultra Shine |
These three sit behind trade login, but understanding the difference matters whether you're a trade customer deciding which to stock, or a customer trying to understand what a quote from an installer actually includes.
| Coating | Layers | Warranty | Best For |
|---|---|---|---|
| Opti-Coat Pro | Single layer SiC | 5 years | Genuine long-term protection at the most accessible professional price point |
| Opti-Coat Pro Plus | Two layers SiC | 7 years | Extra gloss and slickness on top of Pro's protection |
| Opti-Coat Pro3 | Four layers SiC + top coat | 10 years, or lifetime with annual maintenance | Maximum thickness, gloss and chemical resistance, for owners keeping a vehicle long-term |
Pro3's lifetime warranty option requires the vehicle to be checked annually by a certified Opti-Coat installer, similar to how most long-warranty coatings across the industry work. The 10-year warranty with no required maintenance is also available if you'd rather skip the annual appointment.
For installers after 7-year level results without going straight to Pro Plus, we recommend applying Opti-Coat Pro as the base coating and topping it with Opti-Coat Ultra Shine (3 Vehicle Syringe). Ultra Shine is sold in a 30cc syringe covering three vehicles, each with its own 2-year warranty on top of Pro's 5-year base. Both products require certified installer application.
| Hyper Shine | Opti-Coat Pro | |
|---|---|---|
| Chemistry | SiO2 | SiC |
| Applied by | You, DIY | Certified installer |
| Durability | Up to 3 years | 5 years |
| Certified installer required | No | Yes |
| Application style | Easy, wax-like, no high spots | Requires installer training and equipment |
| Best for | Enthusiasts wanting a DIY upgrade | Owners wanting maximum professional-grade protection |
The core difference isn't only who applies it, it's the chemistry and prep involved. Professional SiC coatings typically require full paint correction and controlled application conditions to bond properly, which is why they're restricted to trained installers. DIY SiO2 coatings like Hyper Shine are formulated to be more forgiving, with a longer working time and less reliance on flawless prep, trading some outright durability for accessibility. That trade-off is the same one you'll find comparing DIY ceramic coating against professional ceramic coating across the industry generally, not just within Opti-Coat's own range.
No certified installer application needed for any of these. If you want Opti-Coat's ceramic protection without going through an installer, this is where to start.
Opti-Coat's DIY entry into ceramic coating. Formulated for self-application rather than professional installation, with a 3+ year durability claim, well beyond typical consumer coatings.
When to use it: after a full decontamination and paint correction, on a car you're coating yourself. This is the closest thing to Opti-Coat's professional chemistry available without becoming a certified installer.
A ceramic maintenance sealant that tops up and extends the life of any existing ceramic coating, professional or DIY. Easier and faster to apply than a full coating.
When to use it: as an annual top-up on a coated vehicle, whether the original coating was Opti-Coat Pro, Hyper Shine, or another brand entirely.
A ceramic-infused shampoo designed to clean coated paint without stripping the hydrophobic surface, and to repel airborne contamination between washes.
When to use it: your regular wash routine on any coated vehicle.
A ceramic coating for polycarbonate headlight lenses, combining Opti-Coat resin with UV absorbers to slow yellowing and fading. One tube covers 5 to 6 sets of headlights.
When to use it: after polishing out existing haze or yellowing, to protect the clarity going forward.
Interior fabric and upholstery protection that repels liquids and helps prevent staining on seats, carpets and other soft surfaces.
When to use it: on clean, dry fabric, ahead of the season or event most likely to bring spills into the cabin.
Restores oxidised, faded gelcoat on boats and RVs back to a deep, glossy finish before protecting it.
When to use it: on chalky or dull gelcoat, before applying RV & Marine Wash or a protective polish as part of ongoing maintenance.
Certified installers get access to SiC chemistry most competitors don't offer at retail, plus a brand customers already recognise and trust when comparing ceramic coating quotes.
Harder, more chemically resistant coating means fewer comebacks for etching, staining or premature failure, protecting both the vehicle's paint and the installer's reputation.
Enthusiasts and DIY detailers who want a genuine step up from wax or spray sealant, without booking an installer or paying professional install pricing.
Owners planning to keep a vehicle long-term who want the longest warranty available and are comfortable booking a certified installer for a proper paint protection coating.
Opti-Coat Pro, Pro Plus and Pro3 are professional-install coatings sold only to certified installers, rather than sold as a retail DIY product. This is standard for SiC coatings at this durability tier across the industry, not specific to Detailing Shed.
Hyper Shine is Opti-Coat's ceramic coating built for self-application, with a 3+ year durability claim. It doesn't use the exact same chemistry as the professional Pro range, but it's the closest thing to Opti-Coat's ceramic protection you can buy and apply yourself.
SiC stands for silicon carbide, a harder, more chemically resistant material than the silicon dioxide (SiO2) used in most consumer ceramic coatings. It's the reason Opti-Coat Pro carries a 5 to 10 year warranty where most spray-bottle coatings only claim 1 to 2 years.
Layer count and warranty length. Pro is a single SiC layer with a 5 year warranty, Pro Plus adds a second layer for extra gloss and a 7 year warranty, and Pro3 is four layers plus a top coat, carrying a 10 year warranty or an optional lifetime warranty with annual maintenance by a certified installer.
Yes. Hyper Seal works as a maintenance topper over any existing ceramic coating, not just Opti-Coat's own range.

Opti-Coat is a professional-grade ceramic coating brand developed by Optimum Polymer Technologies, built on silicon carbide (SiC) chemistry. It's applied by certified installers and offers 5 to 10 year warranties depending on the tier, Pro, Pro Plus or Pro3.
Optimum Polymer Technologies is the parent company, founded by chemist Dr. David Ghodoussi. Opti-Coat is Optimum's professional ceramic coating brand. Products under the plain Optimum name, like ONR, Hyper Seal and M-Wash, are generally DIY-accessible, while Opti-Coat Pro, Pro Plus and Pro3 are certified-installer-only.
Hyper Shine uses SiO2 chemistry designed for DIY self-application, not the SiC chemistry used in the professional Pro range. It's a genuine step up from wax or spray sealant and is built to rival professional SiO2 coatings in gloss and slickness, but it isn't the same chemistry or warranty tier as Opti-Coat Pro.
Generally no. Professional SiC coatings like Opti-Coat Pro carry 5 to 10 year warranties, while DIY SiO2 coatings like Hyper Shine typically claim up to 3 years. DIY coatings trade some durability for easier application and no installer booking required.
A typical installation involves Optimum Paint Prep to remove polishing oils before coating, Hyper Polish or Hyper Compound for paint correction beforehand, and Opti-Coat Hyper Seal or M-Wash for ongoing maintenance afterwards.
Yes. Detailing Shed stocks the full Opti-Coat range, both the certified-installer-only Pro coatings and the DIY-accessible products like Hyper Shine, Hyper Seal and M-Wash, shipped Australia wide.
