Corroseal 82331 Water-Based Rust Converter

Restoring my 2005 4runner, this product is fantastic, I had recently purchased a one liter container and as I continue my project, I did not hesitate at all to buy a gallon. Just love this product, extremely efficient

Formidable, certainement le seul véritable convertisseur de rouilles. Merci

I like the fact it neutralized the rust on my boat trailer & 4x4"s

It was expensive but worked well, metal needs to be clean. Easy to apply but make sure to wear gloves and keep skin covered because if you get some on you and it dries it’s hard to get cleaned off

So Far, Very Impressed !! Pick up a screwdriver or paint scraper, wire brush, foam brush, small empty container and neoprene gloves as it's sticky if you get it on you. Pour a little out into a small container (a little goes a long way) and apply to the rusted area. DO NOT POUR UNUSED MATERIAL BACK INTO THE NEW CONTAINER, It will contaminate the jug. I used a product in the late 80's or early 90's on my tailgate on a Ford Ranger that started to rust. It had a different name but it also went on like milk, then turned Black. I've purchased other converters since then that seemed "watered down" and didn't work nearly as effective. I assumed it had something to do with environmental or health concerns as to why I couldn't find it. It was of a different name but this is the same stuff. Worked wonders then, after two coats. It's not passed the test of time yet however, I have used it on my trailer and spots under my truck. This is environmentally friendly, non-toxic, non-corrosive, applies easily. I have nothing bad to say about it so far. Make sure you get all the loose rust off but NOT down to bare metal. It needs a little rust to stick. I had some drip onto the paint on my trailer, no big deal but it did "alter" the color of the paint. On bare metal, it seems to leave a film coating that comes off with my finger nail but over rust, you would have to sand it off. Very glad I found this rust converter again, It works GREAT. I see so many vehicles with rust destroying their cars in Pennsylvania snow/salt state. I can't believe drivers are unaware of this solution, after all, a smaller black patch may not look the best but a larger patch of rust looks much worse and that's where your small rust spot is headed. This may not be a "Professional" repair but it's also not at a "Professional repair cost". Sure, $53 is a lot of money but this stuff works and very easy to apply and over-all, its much less expensive to apply this than to ignore your rust spot. So easy anyone can do this and a gallon goes a long way. Even if you only did nothing to the rust and just applied it over the rust you would be much farther ahead. But if you do that, you'd have to wait until more of the rust flaked off (because it will if you don't first remove the flaking) but apply a little more over where it flaked off and your good to go. Also, if there are "paint bubbles" where rust is developing under the paint, remove the bubble, you will see rust under there. Apply Corroseal. I would highly recommend you get in there with a screwdriver without much pressure and remove the loose stuff and maybe go over it with a wire brush, clean the dust off, dry the area and apply, that's it and your resale value will show the difference as a small patch of this is better than a large patch of rust...You can also paint over this if you want, but you will still the area because it will not have the smooth texture of new paint, it will just hide it a little. Don't forget your undercarriage. If you live in a snow belt state and you have no rust yet, Wash the underside once a week but eventually a stone will break the paint seal and rust will start.
