Its high-cut formula works best with high-speed rotary buffers to quickly strip oxidation and sanding marks without added waxes, fillers, or silicones, and the water-based blend rinses clean for easier finishing.\n\n\u003ch3\u003eHow does this compound remove P800 grit and heavy sand scratches?\u003c\/h3\u003e\n\u003cp\u003eSuper Cut Compound uses a high-abrasion formula tuned to cut through scratches left by P800 and finer abrasives.

If you regularly use a high-speed rotary polisher and need a no-filler compound that cuts quickly and rinses clean, Presta Super Cut Compound is formulated for that role. For best outcomes, follow a multi-step polishing process: cut with Super Cut Compound, refine with a medium polish, then protect with a chosen sealant or wax designed for gel coat.\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use Presta Super Cut Compound on painted fiberglass as well as gel coat?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it can be used on fiberglass coatings and gel coat, but test a small area first and use appropriate pads and speeds for painted surfaces.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need a specific polisher for this compound?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: A high-speed rotary polisher is recommended for optimal cutting performance, though some dual-action machines can work for lighter correction.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Presta","offers":[{"title":"Default Title","offer_id":55170653585751,"sku":"B00EP8FFFI","price":134.72,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/presta-super-cut-compound-front-gallon.jpg?v=1790432440","url":"https:\/\/britishgarage.co.uk\/products\/presta-super-cut-compound-1-gallon-heavy-cut-marine-gelcoat-fiberglass-scratch-remover","provider":"British Garage","version":"1.0","type":"link"}
