CRC 03286 SP-400 Corrosion Inhibitor - 5 Gallon

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.

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.

I bought this because some website reviewed 10 different rustproofing can products in 2019,and this was on top.I was able to cover about 8-10 sq. ft. of the underside of my new SUV a few mils thick as expected before the propellent ran out. It dried semi-tacky with an amber hue when coated over silver metal parts. We just had out first salt truck dump a load this Winter morning, 2 months after I applied it, I am hoping that I can get through the Winter , then will probably apply every year or as needed.

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.

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 really like this product and will buy more. I have one of those Toyota trucks with the frame corrosion problem. This product spayed on smoothly and dried to a nice protective coating. It does have a slight amber color but not noticeable on black. Something to be aware of, it has a strong odor which last about a week. CRC has been around a long time. I remember using their products years ago on commercial aircraft structures.

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.
