Marine XC-300 Fast-Cut Compound

The RUPES Marine XC-300 Fast-Cut Compound is a professional-grade polishing compound developed specifically for marine gelcoat and painted surfaces. Its fast-cutting formula effectively removes P1200, P1500, and finer sanding marks, along with oxidation, scratches, weathering, and other significant surface imperfections.

Engineered for fast, controlled correction, XC-300 restores clarity and brilliant gloss while preparing the surface for final polishing or protection. It is ideal for production gelcoat, oxidized boat finishes, painted hulls, and other marine surfaces requiring strong correction without the aggressive cutting level of an extra-coarse compound.

XC-300 is an excellent choice for boat manufacturers, boatyards, restoration professionals, and marine detailers who need efficient, consistent results.
