Keep your precious steed in tip-top condition with the Muc-Off Harsh Condition Barrier. With a state-of-the-art thin film coating, it'll make light work of rust and corrosion. It's the perfect upgrade for winter months, or to keep your bike looking fresh all year long - as you'll have 12 months of protection. This innovative product is a must-have. It'll keep moisture out, creating a durable anticorrosive layer of protection on your bike's frame, chain, metal parts, plastics and paintwork. And on parts that have already got some rust showing, it'll get rid of it altogether. This replaces the ACF-50 that we have had before!
