Shield Technologies Corporation is the sole provider of Envelop(R) Protective Covers and is the leader in providing the U.S. Department of Defense and its allies with corrosion inhibiting solutions to solve their issues with environmental degradation of aircraft and equipment. Envelop(R) is a custom made waterproof but breathable multi-layered cover technology that actively inhibits corrosion. The U.S. Navy documented a 95% reduction in corrosion over other covers they were using, and found that Envelop(R) lasted 2 -3 times longer than other covers. In fact, most Envelop(R) Covers pay for themselves in the first 90-120 days of use. When you couple all of that with Shield’s world class customer service Envelop(R) just can’t be beat.
