    Default A good rust inhibitor

    Last time I need a rust inhibitor, I used naval jelly. That was long enough ago that something new has to have come out since. Anyone have any good recommendations for a good rust inhibitor?

    I think you need to specify the use. If you were packing a firearm away and burying it on your property in Wyoming cosmoline still reigns supreme.

    Uh, it's not for that purpose, no.

    I have a spare tire well that has a rust perforation and I need to stop it before it gets worse.

    Metal Rescue at Home Depot. Just used it on a motorcycle fuel tank. Works great, non toxic. Removes rust then protects for a period of time.

    On second thought. For a wheel it may not be good as you have to submerge the part in the solution and leave submerged for a period of time.

    Rust inhibitor or removal?

    Removal: the Naval Jelly you mentioned works great and the acid doesn't eat too much base metal. A good old fashion wire wheel is sometimes easier. If high tech is a must, go Laser (https://www.youtube.com/watch?v=Q8q3DZB_l6M)

    Inhibitor: I find paint works great. But if you own a Jeep then tradition requires Cosmoline.

    I'd use it on firearms and maybe my rusted spare tire well, but I wouldn't advise eating food cooked on the surface after the Evapo-Rust treatment.

    we use fluid film in the marine environment on hinges, latches, etc.

    works very well and even brings back full movement to any joint partially affected by rust. more a rust inhibiting lubricant, but it might work for your application.

    I had some rust to treat on the frame of my travel trailer, the manufacturer recommended Rust-Oleum Rust Reformer. I just got done and am pretty impressed. I did minimal prep because it says to only wire brush off flaking paint and I didn't have much of that, just a decent amount of rust. I shook the bottle, poured in plastic cup and brushed on with a cheap paint brush. It brushes on a pale blueish grey but then is supposed to turn black. So far, mine looks like a dark tinted clear coat but the it looks way better without a ton of effort. I did this outside but didn't notice much of an odor.

    Edit: I checked on the the trailer again and where the rust was is almost entirely black as mentioned on the bottle. I think I'll still put some black paint over it for added protection.

    The thing I like the most about this site is when you ask a legit question you don't get answers that start with " I heard, I read, my buddy said, I saw on the internet"......

    Instead you get answers starting with " I used, I tried" etc.

    A great resource for sure!

    Growing up in the rustbelt, used POR a number of times. The others yielded lesser results.

    Is that why Cosmoline sales in California increased 5,000% in December 2017? I still can't believe I lost my assault rifle and high capacity magazines in a boating accident. I don't even own a boat. So annoying.
