Meguiar's M03 Mirror Glaze Machine Glaze outshines other machine-applied polishes, glazes, waxes and sealants. Penetrating nutrients revitalize all glossy paint finishes, restoring their original brilliance and shine. Buffing residue wipes off easily. Safe and effective on fiberglass, plastic and paint. This professional polish leaves a silicone-free surface essential for proper painting in a body shop environment. Formulated for use by hand, rotary buffer or dual action polisher like Meguiar's MT300 DA Polisher.
