Gelcoat Heavy Cut Gh8.01

Koch-Chemie Gelcoat Heavy Cut "Gh8.01" is what you reach for on badly weathered gelcoat and boat paint. This heavy cut pulls out deep scratches, chalky oxidation and scuff marks — the kind fenders leave behind — and lays down serious gloss in the very first pass, even on dark surfaces. It's silicone-oil-free, so you can keep working it for ages without it burning in, and it stays low on dust and sling. Easy to work, it runs on both rotary and dual-action machines.
