Use 85% phosphoric acid but only after comprehensive rotary steel brushing then sanding or sand blasting so as to remove all visible rust so as to get back to bare metal. Then apply 2 coats of phos. acid over 24 hours rinse off with freshwater or better yet distilled water then wipe with metho or alcohol to evaporate any residual moisture then seal with undercoat once fully dry then apply a metal protective topcoat to finish.
I have read a 1000 reviews on Corroseal and 95% of ppl say the same thing... Looks good once applied but rust comes back in 3 months. IT doesn't work very well
The best thing to do is sand all of the rust off by hand, DA sander, or sand blast it off. Rust is tenacious. If there is a little bit left that you cannot get to, I recommend spraying a sealer primer over it followed by a regular primer. Then wet sand after 24 hours, let it dry and then paint it.
Great but what about places you can't do that, or the pits with rust still in them? If used PROPERLY they work better than anything about. Used for decades and they've saved me so much everything. There's a time and place for it.
@@kitjasabsgabs1830 There is a chemical solution you can buy in most hardware stores. It's called "OSPHO". When applied to rusted surfaces, OSPHO causes rust (iron oxide) to chemically change to iron phosphate - an inert, hard, black substance. Where rust is exceedingly heavy, two coats of OSPHO may be necessary. I've tried it recently and it works!!! The rusty part or parts need to soak in this stuff over night or whenever. Give it at least 24 hours. It KILLS rust! You can brush it on with a paint brush, but soaking it is better.
@@3_KNIVES That's what I use and was talking about. If used CORRECTLY, and that's the key word and action is CORRECTLY, you can use any acid and paint with any product. They use acid in so much of things that we buy and use. They don't make iron whatever and prime or paint at that second so they have to have a way to stop or get the part back to perfect condition, Acid. It says that you can wipe with mineral spirits and paint if using Rustoleum oil based paints. I reapply, let set for 5 minutes, scrub with a scotch Brite and rinse with water and dry with air fast, then prime with epoxy and never had any issues. How do you do it? Is there a easier way? Cause alot of ppl are saying I sprayed epoxy then it bubbled up. That tells me they didn't neutralize the acid, clean or prep properly etc. I do it my way and it works. I didn't do this in past and it didn't work and mine bubbled. That was 1998. After I did what I said and alls been fine.
@@3_KNIVES And I spray mine on with an old spray bottle. I wish there was a option to mix with something to make it thicker. Idk what but not like naval jelly but thicker like pancake batter, runs slowly over rated part like a frame so it'll stick.
Ospho or clean and strip phosphoric acid. At Lowes etc it's alot stronger than the ones from auto places. Knock off heavy, use acid, let react, if thick add 1 more coat. If using rustoleum wipe with spirits and prime or paint, if using epoxy, rewet and let sit for 5 minutes, use scuff pad and water and wash off residue. Air dry or with heat and prime and paint. Used since 1998. Autos, heavy machinery, antiques etc. Follow the directions. You will be happy.
This is MISLEADING, I did a search for "rust converter comparison" you were at the top of the list with this video, as you had those exact words in your tag line (title) BUT that is not what your video does, it compares the advertisements of rust converters, while not actually comparing the rust converters themselves. you get a thumbs down for misleading taglines, and poor video information. I hope this constructive criticism and negative feedback helps you do what you say you are going to do in your future videos OR it helps you fade into obscurity so i don't wind up wasting my time watching another one of your videos.

Doesn't actually test anything. Just an Amazon selling Ad that was written by the product lawyer/marking dept's. Best Selling not BEST PRODUCT.

look up vactan
Ospho or Clean and strip. Phosphoric acid from big box home store. Navy has used forever. Can't be crap.

@@kitjasabsgabs1830 You answered your own question. "I do it my way and it works." Good luck and best wishes.
Do these work on Aluminium corrosion?
How about Ospho ?
Vht spray?
you guys out there cam you tell me the best out the 5 for my car chassis
I like Corroseal Juan. I have not tried the others. Corroseal is easy to apply and cleans up easy too.
