Product Overview:

RUPES Marine XC‑100 Extra Cut Compound (9.XC100/1KG) is a high‑performance heavy‑cut compound engineered for removing P800–P1000 sanding marks on gelcoat and fiberglass surfaces.

Ideal for production environments and professional marine detailers, XC‑100 excels on freshly applied gelcoat, oxidized hulls, and heavily contaminated surfaces. Use as the first step in a multi‑stage polishing process, followed by RUPES Marine XC‑300 or XF‑500 for maximum gloss and clarity.
