3D 620 Marine & RV Cutting Compound 946ml - Gel Coat Oxidation Remover
Years of sun and salt leave gel coat chalky, stained and dull. 620 Marine & RV Cutting Compound is built for fibreglass gel coat and painted surfaces on boats and RVs, using 3D's Adaptive Abrasive Technology to deliver a constant cut that removes heavy oxidation, surface stains and scratches up to 1000-grit.
It handles everything from moderate weathering through to severe oxidation built up over years of neglect, and its controlled cut helps avoid the over-working that can damage gel coat. It's filler-free, so the restored surface is genuinely corrected rather than temporarily masked, and the low-dust formula keeps clean-up minimal across large panels.
620 is the cutting step of a two-step gel coat restoration. Run it on a wool pad for maximum cut or foam for a gentler one, then follow it with 630 Marine & RV Finishing Polish to remove any remaining haze and bring the gloss up.
