Meguiars M100 Mirror Glaze Pro Speed Compound is a professional heavy cutting compound that removes severe below surface defects like scratches, acid rain, severe swirls and holograms, and 1200 grit or finer sanding marks without hazing or dulling the finish. Pro Speed Compound was originally formulated to be used by rotary buffer only, but it can also be used by a dual action polisher, like Meguiars MT300 DA Polisher to obtain amazing results. This advanced auto body compound is safe, paintable and contains no fillers, so your defects are actually removed instead of simply being covered up. Follow with Meguiars M210 Mirror Glaze Ultra Pro Finishing Polish to further refine paint and maximize depth of shine before applying a long-lasting wax or sealant, like Meguiars M21 Mirror Glaze Synthetic Sealant 2.0 or Meguiars M27 Pro Hybrid Ceramic Sealant. M100 Pro Speed Compound is available in 32 oz and 1 gallon.
