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

Bought this over the winter and have used it across our fleet - very easy to use. but as i had to realize this summer, it was a big mistake. This stuff turns into oil in the summer, and guess what? It slowly penetrates between the battery posts and the wiring, creating an oil barrier and preventing the transfer of battery charge through the wires and vice versa - the car cannot charge the battery because there is now a thin film of oil between the contacts. Again, great idea but what a nightmare to clean all those battery connections - not to mention we lost 2 batteries due to bad connections caused by this stuff
