TEROSON® WX 400 is a beige, transparent, cavity wax and anti-corrosive agent for protecting all motor compartment cavities, e.g., doors, pillars and sills. It's typically used in garages for spraying cavities in motor vehicle bodies. This is in addition to the existing cavity conservation applied to new cars for follow-up treatment after two to three years, and damage repair after an accident. It's a thixotropic agent with good creeping qualities. The best application results are achieved with the TEROSON® ET CC CUP AIR GUN and the respective probes. It can be applied even at lower temperatures of 10°C (50°F). Its thixotropic nature offers optimum protection even in areas that are difficult to reach, and between narrow sheet metal tolerances. After complete drying, TEROSON WX 400 forms a plastic, non-sticky, water-repellent film.
