Extending paint life and preventing corrosion is the aim of Granitize, and liquid-formula Xzilon is the product. The South Gate, Calif. company notes that Xzilon has been approved for use by major airframe manufacturers Airbus and Boeing.

Testing at the Boeing Materials Technology lab included 1,300 hours of salt-spray chamber exposure, simulated rain erosion on painted and bare metal surfaces, and UV Block/UV30 effectiveness. The company believes Xzilon is particularly effective in a marine environment where corrosion is a factor in paint life.
