Flak Jacket PRO "Full Body Armor" (1 Gallon DIY Spray-On Bed Liner Kit with Gun)

Pro-Grade Armor. DIY Simple.

Stop rust and damage in their tracks. The Flak Jacket PRO "Full Body Armor" 1-Gallon Kit is engineered for the "prosumer" DIYer who demands professional results. Unlike standard urethane products that are formulated to be less durable, Flak Jacket PRO is a superior 2-part polyurea hybrid that provides the extreme durability of a professional spray-in liner with the ease of an at-home application.

With an industry-leading 4,500 PSI tensile strength and 300% elongation, our coating permanently bonds to your surface, creating an air- and water-tight seal that won't warp, crack, or split. It resists scratches, prevents rust, and has a fine, skid-resistant texture that keeps your cargo in place.

This all-in-one kit includes our bundled Astromatic spray gun, calibrated for the ideal 50 PSI application, giving you a consistent, professional-grade texture right out of the box.
