NOCO NCP2 CB104 4 Oz Oil-Based Brush-On Battery Corrosion Preventative, Corrosion Inhibitor, and Battery Terminal Protector Grease

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

This stuff is great. If you clean your post and clamps thoroughly and put this on after clamping it to your battery, you should never have to touch it again till you need to unclamp it. This will last forever and never dry out. I highly recommend this terminal grease.

This really works on battery cable and battery post, to keep corrosion off

Great quality for battery corrosion prevention. A better size and price than the local dealer.

I like the application of this battery terminal protectant. It is great in terms of avoiding waste because I have used the spray version of the same brand. It worked great but was unusable with 1/3 amount left in the bottle. The one fixes that problem. It has same color and durability. However, the texture is like gel and thicker. Therefore, after driving in hot weather, the gel slowly melts down and may become a mess if you apply too much in the first place. So, be careful when applying it onto battery terminals. Though it has this flaw, it is easy to clean and install with a brush-on lid. To sum up, it’s good value for a long time use with one flaw in texture.

Excellent coating. Easy application. Adheres great. Money well spent.

I used to service all my battery posts twice a year. I've had this applied to 3 cars for 3 years now. I haven't serviced a single post since.

Goes on easy and stays were you put it good battery post coating

Applied once and stayed very well for long time.... one year so far and its holding up as corrosion prevention barrier against moisture and acids.

When you buy a spray can you get mostly propellant. This is all product. Also there is no overspray and nozzle to plug off and waste your product.

Works!
