Gtechniq C5 Wheel Armour
C5 is a solvent-carried silicone-oligomer coating engineered for wheels. Its safety data identifies heptane as part of the carrier system. That liquid phase helps the product spread into an exceptionally fine film. As the carrier evaporates and C5 cures, the remaining chemistry forms a durable chemical bond with a properly prepared wheel finish.
That bond explains why our preparation is exacting. Embedded iron, road oil, old dressings, and cleaner residue can sit between the coating and the wheel. We remove that contamination so C5 can meet the finish itself instead of bonding to whatever was left on top.
The cured film has extremely fine surface structure and strong contaminant resistance. Water beads instead of spreading. Brake dust and oily road film still land, but they have less grip and release more readily during washing.
Brake heat can quickly exhaust ordinary wax protection. C5 retains its integrity up to 600°C / 1112°F, so repeated heat cycles do not erase the reason you paid for the treatment.
What this means for you: Your wheels will still get dirty, but brake dust and road film release more easily. That means less scrubbing and fewer harsh cleaning passes on intricate finishes. With correct preparation, a dry 12-hour cure, and proper care, Gtechniq publishes durability of up to two years.
