09/12/01 Dear Mark, Just a short note to let you know how amazing your product is. Sport Optics supplies polarized sunglasses to Transport and Marine industries, fishermen and yachtsmen and a major problem has been hinge corrosion. Since we have been using Lanoguard we have been getting less and less returns. When we do, we apply Lanoguard to the hinges (with great results) before returning them to our customers. We have also found that unlike petroleum-based lubricants, Lanoguard does not react with our lenses. A really great product.
