Store cartridges in a cool, dry place away from direct sunlight. For best adhesion and durability, follow substrate-specific primers and surface-preparation instructions; test adhesion on an inconspicuous area when working with unusual materials. Observe manufacturer safety data for ventilation and skin protection during application.
