Review on 🔋 NOCO NCP2 CB104 4 Oz Battery Corrosion Preventative: Brush-On Oil-Based Formula with Corrosion Inhibitor and Terminal Grease by Paul Barnes

My dead batteries used to be very badly corroded. I've cleaned them up and painted some of them and they look exactly the same as when I put them on a few months ago. Be sure to paint around any metal bands and vents in addition to the connectors. The first time I only did the clamps and there was still growth around the vents and strap. Nothing after repair. EDIT: About 6 months after the first use I again saw a small amount of corrosion on the red connector. However, I won't downgrade his rating as that could be because he didn't completely clean up the corrosion beforehand. Update 05/23/2016: One year later and still no corrosion on any vehicles it has been used on. Update 7/2/2017: Still no corrosion on any of my machines since using this
