Red Line Water Wetter provides corrosion and rust protection for modern aluminum and cast iron cooling systems. A unique additive reduces coolant temperatures by as much as 30 degrees F. This additive can be used in plain water, to provide much better heat transfer properties and protection than glycol-based antifreeze, or can be added to new or used antifreeze to fortify inhibitors and reduce foaming.
Synergyn Super Chill Out is a water wetter solution thats both cheap and effective. Fights rust, corrosion and electrolysis and provides up to 20 degrees of cooler coolant.
