Halfords Alloy Wheel Protector

Chain store giant’s offering is a 500ml spray pack, and was always going to score well on price. But to protect your rims for as long as our winner, you need to use a lot. While the wax-enriched formula was one of the shiniest at the start, it soon faded, and after only two weeks it had all but given up protecting. Simple to apply, like PureX, but not as durable.
