CRC 03286 SP-400 Corrosion Inhibitor - 5 Gallon

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.

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

Dries to a wax. Used on steel wheel on spare tire under pickup truck. Don't know how long it will last

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.

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.

We have a lot of 'condensing' weather here -- humidity above 90%, and often dew-points at the OAT. So, equipment stored in covered but unconditioned spaces often corrodes badly. Since most of our equipment has finished machined surfaces, they MUST be protected from rust.This stuff protects like a seamless coating of epoxy, but just wipes off with a little mineral spirits. I use it, and love it!L

Cons: I wouldn’t recommend using this on spoons and forks because the smell is awfulPros: food does rinse right off no problem and they are rust free.
