This product comes in spray and brush forms, I’m reviewing the spray-on type now. Most lead acid Batteries vent off corrosive gases and sometimes raw acid while charging or just normal use, if the battery is in a car corrosion can develop causing damage over a period of time. This spray-on Corrosion Preventative will neutralize acid before it causes harm, just spray it on the steel mounting plate and areas around the battery (before installing your battery) and the hold-down clamps. Always spray on and around the battery posts. I use NOCO NCP2 MC303S Battery Corrosion Terminal Protector rings before putting the battery cables on, these will also add more protection to help prevent battery corrosion. It doesn’t cost much to protect your investment and help keep your car battery in top shape. Corrosion can cause a battery to discharge as the acid allows the positive side to find ground slowly shorting the battery. A simple test with a volt meter will show this just connect the negative end of your meter to your battery and hold it, now use the positive end of your meter to the battery case near the positive post or vent caps, if you have any acid or corrosion you’ll see a small voltage reading. If so clean your battery with hot water with backing soda, it will foam up at first but should soon clear up, rinse with just warm water. Once dry spray with NOCO NCP2.
