It is designed as a polishing step to be used after cleaning and before waxing or sealing, restoring optimal gloss that washing alone cannot bring back. The gel formula contains rich polishing oils that feed and nourish fiberglass and painted surfaces, helping revive depth and shine rather than just masking dullness on the surface. It is especially effective on dark-colored hulls and gelcoat, where oxidation and fading are most visible and a deep, wet-look shine makes the biggest difference in appearance.\u003c\/p\u003e\u003cp\u003eThis polish can be applied by hand or with a machine, including a dual-action polisher or a high-speed rotary buffer, giving owners flexibility whether they are doing a quick touch-up or a full detailing job. It is unscented and supplied as a liquid contents gel in a 16 ounce bottle. Because it is a polish rather than a combined cleaner-wax, it is intended to restore gloss and nourish the surface before a separate coat of wax or sealant is applied for protection. It is suitable for use on boats and RVs wherever fiberglass, gelcoat, or painted surfaces need their shine restored.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Meguiar's\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e M-4516\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Boat Wax\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Form:\u003c\/strong\u003e Gel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 16 Fluid Ounces (473 Milliliters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScent:\u003c\/strong\u003e Unscented\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Recommendation:\u003c\/strong\u003e Gelcoat, painted, and fiberglass surfaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Method:\u003c\/strong\u003e By hand or machine (dual-action polisher or rotary)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 070382145163\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is Meguiar's Fiberglass Boat Polish used for?\u003c\/strong\u003e Meguiar's Fiberglass Boat Polish (M-4516) is used to create a brilliant high gloss finish on fiberglass, gelcoat, and painted marine surfaces after they have been washed, restoring shine that cleaning alone does not bring back.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a wax or a polish?\u003c\/strong\u003e M-4516 is a polish, not a wax.
