H&H CB12 Corrosion Block, 12-Ounce Aerosol Can

Great product keep my Outboard looking new, safe to Spray everything under the cawling

By far the best Corrosion protection product. Purchased a boat from Texas, 20 years ago with a bit of corrosion on some of the hardware. Used this product shortly after purchasing and it stop any further corrosion, to date. I do properly winterize at the end of every year.

Product is easy to use and excellent for correcting intermittent electrical connections on low voltage circuits. Also works amazingly well on keyed door locks. Lasts a long time (years) with proper re-application. Targets the invisible corrosion often occuring between copper circuit boards and tin connectors.

I had corrosion on my motorcycle fins and I went on youtube and watched a few videos on dealing with it. Oils were used in the videos such as Aerokroil Oil so I had some and tried it as well as WD40. Other oils were recommended such as Marvel Mystery Oil, of which I had none. All the oils I did apply and let sit all week till my next weekend ride cleared up the appearance of the bubbling of the aluminum corrosion, but after my ride and the oils burnt off and the corrosion was apparent again. One oil that was on another video was H&M CB12 Corrosion Block. I ordered a can and put it on last week and drove my bike today. When I got back home NO signs of corrosion! No matter where you park your bike please oil down you engine parts to ward off corrosion. It will not harm the paint but will keep your bike looking show-room-new! I wish I had known to do this. Best to you all!

This is an excellent product. We live near salt water and use it on hose spigots, metal exterior door knobs, electronics and anything else that can corrode. The motor on our outdoor fan on our patio was making a loud hum, thought it was on its' way out, sprayed the motor at least 4 years ago and it's been quiet ever since. Also sprayed a rechargeable vacuum that I leave on the patio. It wouldn't run so we cleaned it up, sprayed with corrosion block and it's running again. It's been on the covered patio for 11 years, and was at least 5 when we moved here and put it out there. We call this stuff "Magic Spray". The price was great in comparison to other vendors and the shipping was quicker than promised.

This stuff works great. I use it on my bronze statues to clean them up. I also took to work and used on the bathroom stalls on the metal fixtures works great.

I have used corrosion block for many many years. I highly recommend this product, especially if you’re in saltwater conditions. It definitely prevents Rust. I recommend this product and the Amazon price is much cheaper than any Marine store.

The product is superior in the fact it dissolves rust AMAZINGLY (by far the leading product), but in the same vein, it collects a lot of dirt & grime and isn't a great lubricant. In my opinion, it is the best rust remover, but in removing rust you'll have to apply lubricant, which means you'll have to purchase a different lubricate (depending on the job you're doing). I was removing the rust under my vehicle from automatic carwashes (the fastest way to destroy your undercarriage and create rust, FYI) so I need a better protectant for the undercarriage. If you are doing smaller-sized projects, then this product will work fine for your need most likely. Hope this helps.

Spr and keep it looking neway this on your outboard

Great product for using appropriately.

Pleased I was able to fine this online

Thought it was going to stop the battery from working after spraying it on my battery connection but after a mile or so the battery started to work but l haven't ride my bike in the rain not sure weather it has made a difference yet
