We fabricate each 3M™ Polyurethane Protective Boot from tough polyurethane and pre-form it for exact-fitting protection. The 3M™ Polyurethane Protective Boot SJ8681HS is paintable and can be applied over painted surfaces and forms a protective barrier between vulnerable surfaces and damaging elements. These products perform equally well on metal and composite materials. Our boots are one of the most economical and effective solutions available to protect those high value assets that are subject to damage.
