Pettit Protect 14700/1470122 High-Build Epoxy Barrier Coat, Grey, Quart
Pettit Protect is a high-build epoxy priming system engineered for two jobs: preventing gelcoat blistering before it starts and repairing hulls that already have blisters. The system lays down a thick, dense film of epoxy that dramatically slows water absorption into the laminate, which is the root cause of osmotic blistering. Beyond moisture resistance, the cured film stands up well to chemicals, corrosion, and abrasion, making it a durable base coat below the waterline or anywhere a tough epoxy barrier is needed.
Pettit Protect is formulated to bond to a wide range of substrates, including fiberglass, aluminum, steel, and other metals, so it works as a system primer across most hull materials. On lead keels, the recommended prep is disc sanding or abrading to bright metal, followed by a coat of Metal Primer, a coat of Pettit Protect, and fairing with Pettit 7050 EZ-Fair Epoxy Fairing Compound if needed before two additional coats of Protect. On steel or cast iron keels, bright-metal prep is followed by a coat of Rustlok Steel Primer (overcoated within 1/2 to 2 hours, no more and no less), then Pettit Protect and fairing as needed. Pettit Protect can also be applied over sound, existing two-part epoxy finishes after brush-off sandblasting or heavy 60-grit sanding, using three coats per the instructions. Total dry film thickness matters more than coat count: on metal and fiberglass, 12 mils total DFT should be achieved, adding coats as needed to reach it. This quart of Pettit Protect is supplied in grey.

Frequently Asked Questions
What is Pettit Protect used for? Pettit Protect (part number 14700/1470122) is a high-build epoxy priming system used both to prevent gelcoat blistering and to repair hulls that already have blisters, by building a thick epoxy film that resists water absorption.
Will Pettit Protect work on my hull material? Yes, this epoxy barrier coat is suitable for fiberglass, aluminum, steel, and other metal substrates, making it a system primer for most common hull materials.
How much does one quart of Pettit Protect cover in terms of coats? A quart is intended for building multiple coats toward the recommended 12 mils total dry film thickness on metal and fiberglass; the exact area covered depends on how many coats are applied to reach that thickness.
How do I prepare a lead keel before applying Pettit Protect? Disc sand or otherwise abrade the lead keel to bright metal and clean off residue, then apply one thin coat of 6455/044 Metal Primer, let it dry eight hours, and follow with a coat of Pettit Protect.
How do I prepare a steel or cast iron keel before applying Pettit Protect? Abrade the steel or cast iron keel to bright metal, clean off residue, then apply one coat of 6980 Rustlok Steel Primer and overcoat with Pettit Protect within 1/2 to 2 hours, no more and no less.
Can Pettit Protect be applied over an existing epoxy barrier coat? Yes, Pettit Protect may be applied over existing two-part epoxy finishes that are in sound condition, provided the surface gets brush-off sandblasting or very heavy sanding with 60 grit sandpaper, followed by three coats of Pettit Protect.
What if my existing bottom coating is in poor condition? Any existing two-package epoxy finish in poor condition, along with one-package primers and bottom paints, should be removed completely down to the appropriate bare substrate before applying Pettit Protect.
What color does this quart of Pettit Protect come in? This listing for Pettit part number 14700/1470122 is supplied in grey.
Do I need to fair the surface after priming with Pettit Protect? If fairing is required, apply Pettit 7050 EZ-Fair Epoxy Fairing Compound after the initial coat of Pettit Protect, sand smooth, and then apply the remaining coats of Pettit Protect per label directions.
How many coats of Pettit Protect do I need? Coat count is secondary to total dry film thickness: on metal and fiberglass, the goal is 12 mils total DFT, and additional coats beyond the typical two to three should be added if that thickness is not reached.
Is Pettit Protect resistant to chemicals and abrasion? Yes, once cured the high-build epoxy film from Pettit Protect offers strong resistance to chemicals, water, corrosion, and abrasion.
What size container does Pettit Protect 14700/1470122 come in? This product is packaged as a 1 quart bottle of liquid epoxy barrier coat.
