Diamondbrite
Quick answer: Diamondbrite is a dealer-applied paint and interior protection system from Jewelultra. Its current two-stage nano/advanced ceramic treatments create a high-gloss protective skin and are backed by a UK lifetime guarantee when applied by approved installers and maintained as specified.
Jewelultra Diamondbrite is a name familiar to many in the UK as they provided dealership coating packages. They have now switched to a ceramic coating, but for many years supplied a professional polymer coating. This was a product we supplied for over a decade.
What it means
Diamondbrite markets a two-stage nano/ceramic paint protection alongside fabric and leather protectors. The range includes “Advanced Ceramic” and “Nano Ceramic” variants for automotive, leisure and marine, positioned to make cleaning easier and resist environmental fallout. Product literature highlights a durable, glossy barrier and “no need to polish” claims when the system is maintained per instructions.
Why it matters
- Dealer pathway: commonly offered at point-of-sale with registration and handover pack.
- Ease of care: hydrophobic behaviour aims to reduce cleaning effort and frequency.
- Warranty signal: lifetime guarantee in the UK (terms apply) provides a clear aftercare framework.
Where you’ll see it
Franchised and independent dealers, leisure/marine retailers and approved applicators that register the guarantee after installation.

Car Paint Protection; Brands; Dealer-applied protection; Maintenance
Maintenance & guarantee (at a glance)
- Registration: the treatment is typically registered post-install to activate the guarantee.
- Aftercare products: Diamondbrite supplies a non-foaming “Conserver” and care items to maintain behaviour.
- Scope: guarantee describes protection against specified environmental damage to paint and interior staining when maintained as directed.
Common mistakes
- Assuming the guarantee equals “fit-and-forget” – routine washing and the specified aftercare are still required.
- Comparing dealer packages directly with pro PPF or installer-grade ceramics without considering prep, thickness and film type.
- Skipping proper decontamination/panel prep before application, which can weaken bonding and shorten real-world life.
- Relying on strong TFRs weekly – heavy alkaline/acid routines can mute hydrophobics and increase spotting risk.
