Imperial Marine Compound & Finishing Material - for Gelcoat
3M's flagship product for gelcoat refinishing and mold work. This combination compound and polish is designed to take dull, or repaired, gelcoat to full gloss with just a single product. It combines a fast cutting compound with a fine finishing material. As you buff, the coarser compounding particles degrade as they remove oxidation, leaving the finer abrasives which polish the surface to a gloss finish.
Note - This product is less aggressive than the similar sounding Compound and Finishing Material (MMM 36044 and 36045).
