3M Perfect-It Gelcoat Compound + Polish 30345 delivers professional-grade results for RV, marine, and industrial surfaces in a variety of climate ranges. This innovative solution works as a single-step compound plus polish or as a second-step finish. Operators can use the high-performance formula to help remove oxidation, blemishes and scuff marks, as well as P1000 and finer grade scratches - especially on dark-colored gelcoats. Engineered with productivity in mind, the fast-cutting, fine-finishing compound plus polish helps decrease sling. Plus, the long wet time extends product life and makes cleanup easy. To further reduce compounding time, refine sanding marks with 3M Trizact 1500 discs or finer before compounding. 3M Perfect-It Gelcoat Compound + Polish 30345 provides high gloss and a fine finish in a variety of gelcoat applications.
