CRC Sp-400 Corrosion Inhibitor, 10 Wt Oz, Seals Out Moisture Completely For All Bare Metals, Long-Term Indoor/Outdoor Protection, NSF H2 Registered, Aerosol Spray

Have used this product for 30 years as a battery protectant on golf car batteries. Works extremely well. You can break the connection and out it back together and still have great protection. Won't wash off, and it drys which is nice. Doesn't get all over you like the red stuff .

This stuff is great for keeping your tools and equipment from rusting. Mine have been taking a beating out in my unheated garage, where temperature swings and humidity cause condensation to form on everything, so my tools look like they've been left out in the rain. Now I just cover anything susceptible to rust with this stuff. I thought I'd have to clean this stuff off before I could use my tools, but in most cases it isn't necessary. It's sticky and greasy when it goes on, but it dries to a thin film after a few days. If you have equipment like wheelbarrows or wagons that tend to get left out, and you hate to let them rust but don't have time to keep them painted, just spray them with this. If the surface is already covered in rust, this stuff just soaks in and keeps it from rusting further.Incidentally, a few months ago I laid some small metal parts on a piece of scrap lumber to spray them. When I was done I tossed it pack on the pile. Now I'm noticing that it hasn't weathered where the rust inhibitor is. This might be a quick way to preserve unfinished wood that isn't worth painting or varnishing.

This is a great sticky oil for metal parts exposed to moisture that not painted. Great coating for in door automotive lock mechanisms and window roller guides instead of that white lithium grease.

Good stuff. Use it on outdoors eqipment, like bottom of gas grill. Or spray in usually inaccessible areas in car trunk whick get exposed to moisture. Useful on stored tools as well. For very valuable tools, clean well, spray, allow inhibitor to set up, and roll prepped tool in waxed paper. Now the tool will withstand stoage even in damp areas, although drier storage always makes more sense. I keep my car jacks prepped this way, ready to go if needed, with the moving parts lubed by the wax.Goes on easy, but sets up as a heavy wax. CRC product are usually 100% reliable, too

I love the fine mist spray making application easy and controllable. It smells like crayons and can be sticky. Spray lube like pb50 or mineral spirits will remove it. This will not wipe off easy without some type of oil or solvent therefore its not recommended for daily use. I use it on cast iron work surfaces of my power tools when not in use.

This is the best heavy duty corrosion inhibitor you can buy, period. It forms a tough protective film that dries in time to where you an handle the item without mess or disturbing the film. It does not stay waxy like Boeshield. It is not a light penetrating film like Corrosion-X. This product use to be called " CRC Mold Saver", which I took to mean it was developed to protect molds from corroding when stored between uses. It was renamed SP-400.

This is 45 45 10 in a spray can. Cast up some lead bullets, spray on some CRC and gently tumble. A little goes a long way. This is better than 45 45 10. This is better than Lee ALOX. This stuff dries fast and is not sticky or gummy. You don't have to be Mikey to try it and like it.

Use SP-400 all the time for protecting bare metal from rust and it works awesome however the can is the worst. Used it one time and placed it on the work bench and the next morning to my surprise the can slowly leaked out all the propellant and most of the contents. Seems to be a common problem with some cans.
