C5 provides the best protection for wheels, whether standard or alloys. Because of C5’s unique, exceptionally fine surface rheology and chemical bonding mechanism, its performance is outstanding. The former property gives the coating its excellent stain and contaminant resistance, and the chemical bond formed between the wheel surface and C5 makes the coating durable. With 1 to 2 years durability, C5 repels brake dust making your rims very easy to keep clean.
