DiversiTech Clear Coil Guard Aero 18oz HVAC Coil Coating Spray for Corrosion & Salt Protection CG-AER
Protect your HVAC investment from corrosion, salt air, and harsh environmental conditions with the DiversiTech Clear Coil Guard Aero 18oz. Designed specifically for condensers and evaporator coils, this professional-grade coating creates a durable, invisible barrier that extends equipment life without compromising performance.
Ideal for coastal environments where salt exposure accelerates rust and coil deterioration, this fast-drying acrylic formula delivers immediate protection against salt spray, chemicals, and weathering. Unlike traditional coatings, it maintains full heat transfer efficiency, so your system runs just as efficiently while staying protected.
The aerosol application makes it easy to apply evenly across coil surfaces, while the high dielectric properties help reduce the risk of electrical shorts during operation. Whether you’re protecting new equipment or extending the life of an existing system, this is a simple, cost-effective solution for long-term reliability.
