Its high-solids formula lays down a thick film in fewer coats than typical barrier systems, reducing water absorption into the laminate and making it a strong choice for osmotic blister prevention and blister repair below the waterline. Beyond fiberglass hulls, Pettit Protect also provides dependable corrosion protection on underwater metals, including steel, aluminum, and other metal surfaces, and can be applied over lead or steel\/cast iron keels once properly prepared.\u003c\/p\u003e\u003cp\u003eApplication follows a defined surface-prep and buildup sequence: bare lead keels are abraded to bright metal and primed with Metal Primer before Pettit Protect is applied; bare steel or cast iron keels are abraded and primed with Rustlok Steel Primer, allowed to dry only 1\/2 to 2 hours before overcoating. Where fairing is needed, Pettit 7050 EZ-Fair Epoxy Fairing Compound is applied between coats and sanded smooth. Pettit Protect can also be recoated directly over sound existing two-part epoxy finishes after brush-off sandblasting or heavy sanding, while finishes in poor condition, one-package primers, and bottom paints must be removed entirely first. Total dry film thickness matters more than coat count; on metal and fiberglass, additional coats beyond three are recommended if 12 mils total DFT is not reached. This gallon container is finished in gray with a gloss sheen and is applied by brush or roller.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Pettit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 14700\/1470106\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Gloss\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Size:\u003c\/strong\u003e 1 Gallon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePaint Type:\u003c\/strong\u003e Two-Component Epoxy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Surfaces:\u003c\/strong\u003e Fiberglass, Steel, Aluminum, Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Method:\u003c\/strong\u003e Brush, Roller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Total Dry Film Thickness:\u003c\/strong\u003e 12 mils (metal and fiberglass)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 13.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 725469020306\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is Pettit Protect used for?\u003c\/strong\u003e Pettit Protect is a two-component epoxy barrier coat used where maximum resistance to fresh or salt water is required, most commonly as an osmotic blister prevention and repair coating on fiberglass hulls below the waterline.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill Pettit Protect stop or prevent blisters on a fiberglass hull?\u003c\/strong\u003e Yes, its high-solids epoxy formula reduces water absorption into the laminate, which is why Pettit Protect is used for both osmotic blister prevention and blister repair work.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan Pettit Protect be applied to metal keels?\u003c\/strong\u003e Yes. Lead keels should be sanded to bright metal and primed with Metal Primer first, while steel or cast iron keels are abraded and primed with Rustlok Steel Primer before Pettit Protect goes on, and it also provides corrosion protection on underwater metals generally.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long should I wait before recoating over Rustlok Steel Primer?\u003c\/strong\u003e On steel or cast iron keels, Rustlok Steel Primer should be allowed to dry only 1\/2 to 2 hours before the first coat of Pettit Protect is applied, no more and no less.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many coats of Pettit Protect are needed?\u003c\/strong\u003e Coat count is less important than total dry film thickness; on metal and fiberglass surfaces, if three coats do not reach 12 mils total DFT, additional coats of Pettit Protect are recommended until that thickness is achieved.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this gallon of Pettit Protect be applied over an existing epoxy barrier coat?\u003c\/strong\u003e Yes, provided the existing two-part epoxy finish is in sound condition. It requires brush-off sandblasting or very heavy sanding with 60 grit sandpaper first, followed by three coats of Pettit Protect.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat if my existing bottom paint or primer is in poor condition?\u003c\/strong\u003e Any two-package epoxy finish in poor condition, along with one-package primers and old bottom paints, should be removed completely before applying Pettit Protect, following the appropriate bare-substrate prep steps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs fairing compound needed with this product?\u003c\/strong\u003e Only if the hull or keel needs fairing. In that case, Pettit 7050 EZ-Fair Epoxy Fairing Compound is applied after the first coat of Pettit Protect, sanded smooth with 80 grit sandpaper, and followed by two additional coats of Pettit Protect.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color and size does Pettit Protect come in?\u003c\/strong\u003e This listing is the gray, gloss-finish 1 gallon container of Pettit Protect, part number 14700\/1470106.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is Pettit Protect applied?\u003c\/strong\u003e Pettit Protect is applied by brush or roller as part of a two-component epoxy system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat surfaces is Pettit Protect suitable for?\u003c\/strong\u003e Pettit Protect is recommended for fiberglass, steel, aluminum, and other metal surfaces, including lead and steel or cast iron keels once properly prepped and primed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this gallon of Pettit Protect weigh?\u003c\/strong\u003e A gallon container of Pettit Protect (part number 14700\/1470106) weighs 13.7 pounds.\u003c\/p\u003e","brand":"Pettit","offers":[{"title":"Default Title","offer_id":48991714279643,"sku":"PET-4700-4701-G","price":167.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/71fQBWsNLrL.jpg?v=1784510397","url":"https:\/\/www.goodvibesmarina.com\/products\/pettit-protect-high-build-epoxy-barrier-coat-gray-1-gallon-two-part-osmotic-blister-prevention-underwater-metal-protection","provider":"Good Vibes Marina","version":"1.0","type":"link"}
