NOCO NCP2 CB104S 4 Oz Brush-On Oil Based Battery Corrosion Preventative

Worked great, had pretty bad corrosion issues but was too cheap to replace the battery. These lasted over a year till I sold the car.

I'm not sure about the other guy's quantity problem, but these are not only the best terminal protectors, in my shop I've found they are the ONLY terminal protectors that actually work. I just received another new jar from a local auto parts house (at a considerably higher price than Amazon), and while I'm not going to count them, the jar is full. Don't waste your money on other brands, especially the ones that are red for positive and green for negative. This NOCO product with the thick oozy red material prevents all corrosion from forming on battery terminals. The battery tie-down bar will still corrode, but there will be NO corrosion on the actual terminals or cables. ** UPDATE ** Since my last review, I have purchased another can of these, but this time from Amazon. I was very surprised to find THEY ARE NO LONGER RED! The thick, oozy red material is not there. Now it is clear. I called the company and the rep told me the red is simply a coloring dye that in the interest of a cleaner looking engine compartment has been eliminated. The clear doesn't look as messy. He assured me the product is exactly the same and will work just as well as it always has. I hope so.

I find that this works much better than the spray because you can put the product right where you want it and it seems to stick to the posts and last longer than the spray

Works great, very easy to use and great value!
