- Muc-Off Harsh Conditions Barrier uses a state-of-the-art, thin film coating to give your bike long term protection against rust and corrosion. It even works on surfaces that already have rust… it simply stops rust in its tracks, removing it altogether! Particularly effective in very harsh conditions, our formula is ideal for protecting your two-wheeled toy over the winter months when large amounts of road salts are out on the roads. The innovative treatment drives out moisture, creating a durable anticorrosive all-weather barrier on your bike’s frame, chain, metal parts, plastics, and paintwork. Designed to continually penetrate corrosion, Muc-Off Harsh Conditions Barrier will spread into the tightest micro cracks and seams to remove moisture and salt-water. We’ve also added a UV application dye so you can check that every area you want to protect is treated and the maximum protection is always in place with a UV torch. Suitable for use on bicycles, ebikes and motorcycles.
