IGL Coatings Review: Kenzo, Quartz+ and the Graphene Claims

IGL markets Kenzo as reinforced with what it calls Graphene Infinite, built as a two-component system combining a K1 base coat and K2 top coat. The graphene in the formula is structured as platelets, multiple layers of graphene sheets stacked together, which IGL says improves hydrophobic performance, heat resilience and gloss depth compared to a non-graphene SiO2 coating at a similar price point. This is a real structural difference from a plain nanoceramic coating, not just an ingredient added for the marketing copy.

The practical benefit buyers notice most is easier washing: a lower slip angle means water and light contaminants release from the surface at a shallower angle than on standard ceramic coatings, which is a genuine quality-of-life improvement during routine maintenance.

Both IGL coatings use graphene reinforcement, but at different concentrations and price points, putting them in different competitive tiers within this comparison set.

Pencil hardness testing, the method most ceramic coating brands reference, has a practical ceiling most of the industry treats as 9H. When a brand like IGL or Gtechniq publishes a 10H figure, it reflects that specific brand's own testing methodology and equipment, not a verified step beyond what every 9H-rated competitor achieves. That does not make the claim dishonest, but it does mean you should not choose Kenzo over a 9H-rated coating like Opti-Coat Pro Plus or CarPro CQuartz Professional purely because the number on Kenzo's label is higher.

What matters more in practice is the published durability window and warranty backing behind each number, which is where Kenzo's up-to-5-year rating genuinely competes with Ceramic Pro Silver and sits below Gtechniq Crystal Serum Ultra's 9 year term.

Ecocoat Quartz+ is IGL's answer to the CarPro CQuartz UK 3.0 and Ceramic Pro Silver price tier, and it competes well there: graphene nanoplatelet reinforcement at a price closer to entry-level coatings than to flagship pricing. The UK registration program that extends coverage from 4 to 8 years is a meaningful bonus if your installer offers it, though buyers outside that specific program should expect the base 4 year rating as the realistic baseline.

Where Quartz+ can disappoint is if a shop prices it near Kenzo levels without clearly explaining the durability and hardness gap between the two products. Confirm which specific IGL product is being quoted before paying.

Yes, with the hardness-number caveat in mind. Kenzo offers a legitimate 5 year, graphene-reinforced alternative to Ceramic Pro Gold or Feynlab Heal Lite at a generally lower installed price, and Quartz+ undercuts most entry-tier competitors while still offering real graphene reinforcement. IGL's installer network is smaller than Ceramic Pro's or CarPro's, so availability is the main tradeoff, not product quality.

IGL also publishes clearer regulatory documentation than several competitors, listing compliance across TSCA in the US, AICS in Australia, ECHA in the EU and KECL in South Korea directly on its product pages. That level of disclosure is uncommon in this category and is a reasonable proxy for how seriously a brand treats its own technical data sheets, which matters when you are trying to verify a durability or hardness claim beyond the marketing copy.

The growing number of independently owned detail shops carrying IGL alongside more established brands is itself a useful signal. Installers generally do not add a second or third coating line to their menu unless customers are specifically asking for it, which suggests Kenzo's reputation is spreading through word of mouth rather than paid placement alone.
