Professional Si Ceramic Protection

Diamond hardness engineered for your wheels

Diamond Shield is a nano-ceramic coating engineered specifically for alloy wheels — chemically bonding to multiple wheel finishes, including powder-coated and lacquered surfaces, for a hard, hydrophobic barrier against brake dust, road salt, and UV.

How to apply

Four steps, one wheel at a time.

Designed around the included finger applicator pad for precise control across barrels, spokes, and lips — no block applicator required.

01

Prep the wheel

Wash and decontaminate thoroughly. Dry completely — the surface must be free of dust, oil, and residue before coating.

02

Load the pad

Apply a few drops of Diamond Shield to the finger applicator pad included in your kit.

03

Coat in sections

Work the coating into the wheel section by section, using the pad's shape to reach spokes and inner barrels.

04

Buff and cure

Once beading appears, buff excess with the microfibre cloth. Keep dry for 24 hours; full cure at 48 hours.

Questions

Before you buy

How long until I can drive after applying?

Keep wheels away from water and road contamination for the first 24 hours. Full chemical and abrasion resistance is reached after 48 hours.

How many wheels does one kit cover?

Coverage depends on wheel size and condition, but 30ml is designed to comfortably cover two full sets of four alloy wheels with careful, sparing application.

Where can I find the full safety information?
