3M Perfect-It III Extra Fine Plus Compound 1L. Designed for use with standard 2K paint systems. Use to remove fine sanding and coarser compound scratches as well as removal of orange peel. This is a core product in the 3M paint rectification system. Recommended for use after initial application of Fast Cut Extreme Compound (green top). After using Extra Fine Compound, use 3M Ultrafina for removing swirls or holograms for a perfect final finish. May be used by hand but for best results use a polisher.
