Great product, works perfect on cars and my boat.
I've used this for decades, it's proven corrosive prohibitor. I respray everytime I change the oil. I also use on my Ranger boat batteries. High quality, great value.

Good stuff.
This protector works real good. Saves having to clean the battery post. Just follow the directions. Best if you wear disposable gloves.

A must for your lead-acid battery post.
This stuff does work. I was having trouble with corrosion on the hot post of my mower battery. Cleaned off the post and connector, sprayed them with CRC 05046 and no more corrosion.

Good product but will not do business with this seller again
Product is fine. My beef with 3rd party All World Auto is that they used a usps priority mail bubble pouch as packing material. Though it's free, and bubble wrap can be expensive, it's unprofessional and unethical of them (and actually a violation of federal law).

Long-Lasting Battery Protection with Easy Maintenance
I tried this product a few months ago for a battery replacement, and I'm amazed by the lasting red coating it provides. With enough volume, I can top it up annually if necessary. Pairing it with foam-soaked anticorrosion ports ensures my car always starts up smoothly. Highly recommend!

Battery Terminal Protector
I have three vehicles and one golf cart, and I use this terminal protector on all of them. I live in the south where the humidity is very high in the summer. The terminals stay clean and clear of corrosion all year long.
