Mini 4WD 520 Bearing Polishing Compound WRC (Wide Range Compound) Capacity: 10g Includes original logo sticker This polishing compound is formulated specifically for polishing 520 bearings used in Mini 4WD rollers, etc. It's a unique blend developed based on several polishing compounds originally designed for other purposes, balancing smooth roller rotation and ease of use. Advantages: * The compound dissolves in water, allowing for dilution and adjustment of polishing speed. * Easy to clean due to the water-soluble nature of the compound. * Prevents roller detachment caused by excessive pressure removal. * Can sometimes restore bearings that would otherwise be discarded. Disadvantages: * Excessive polishing can lead to bearing damage. * Bearings require more frequent lubrication after polishing due to the lack of oil. No discounts available. The container shown in the first image will be shipped in an envelope. Please contact us before purchasing multiple items. Information about WRC is available on "X".
