It is used to degrease the surface and remove contaminants such as wax, oil, and mold-release residue that can prevent primer or paint from bonding properly. Proper surface preparation is a critical first step in any marine painting or refinishing project, whether the job involves antifouling paint on a fiberglass hull, primer coats on underwater metals such as bronze or stainless steel shafts, struts, props, trim tabs, and thru-hull fittings, or a barrier coat system such as InterProtect. Applying this surface prep before priming and painting helps the subsequent coats adhere evenly and last longer, since finish coats are only as good as the surface underneath them. This product is sold as a full gallon, making it suited for larger hull or component prep jobs where multiple coats of primer and antifouling paint will follow. It is part of the Interlux line of marine coatings and surface preparation products used alongside items such as Viny-Lux Primewash, InterProtect, Fiberglass Bottomkote, and Trilux antifouling paints.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Interlux\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 5608731\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Marine Primers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Gallon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 9.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 081948001366\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is Interlux Fiberglass Surface Prep used for?\u003c\/strong\u003e Interlux Fiberglass Surface Prep (part number 5608731) is a solvent wash used to degrease and clean fiberglass, gelcoat, and metal surfaces before priming and painting, removing residues that can interfere with paint adhesion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size does this come in?\u003c\/strong\u003e Part number 5608731 is sold as a full gallon of Interlux Fiberglass Surface Prep.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this be used on metal parts like props and shafts?\u003c\/strong\u003e Yes, Fiberglass Surface Prep can be used to degrease underwater metals such as bronze and stainless steel shafts, struts, props, trim tabs, and thru-hull fittings prior to painting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need this before applying antifouling paint?\u003c\/strong\u003e Degreasing the surface with Interlux Fiberglass Surface Prep is recommended as a preparation step before applying primer and antifouling paint coats, since a clean surface improves paint adhesion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this the same as Fiberglass Solvent Wash 202 or Special Thinner 216?\u003c\/strong\u003e Interlux Fiberglass Surface Prep (5608731) serves the same surface-degreasing role referenced alongside Fiberglass Solvent Wash 202 and Special Thinner 216 in Interlux surface preparation procedures.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does a gallon of this weigh?\u003c\/strong\u003e A gallon of Interlux Fiberglass Surface Prep, part 5608731, weighs 9.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of product is this?\u003c\/strong\u003e Part number 5608731 is categorized as a marine primer\/surface preparation product within the Interlux line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this work with InterProtect or Viny-Lux Primewash systems?\u003c\/strong\u003e Fiberglass Surface Prep is used as a preparatory degreasing step ahead of coating systems such as InterProtect 2000E\/2001E and Viny-Lux Primewash 353\/354.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this product?\u003c\/strong\u003e The UPC for Interlux Fiberglass Surface Prep, part 5608731, is 081948001366.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this suitable for aluminum surfaces before applying Trilux paint?\u003c\/strong\u003e Degreasing aluminum surfaces before applying Trilux antifouling paints is part of the surface preparation process that Interlux Fiberglass Surface Prep is intended for.\u003c\/p\u003e","brand":"Interlux","offers":[{"title":"Default Title","offer_id":49025089405147,"sku":"ILX-601G","price":106.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/41vMqsbOIVL.jpg?v=1785330996","url":"https:\/\/www.goodvibesmarina.com\/products\/interlux-fiberglass-surface-prep-gallon-part-5608731","provider":"Good Vibes Marina","version":"1.0","type":"link"}
