Corroseal Rust Converter is an elite, industrial strength product for all marine, household, automotive, and industrial rust problems. Rust occurs naturally when the iron in steel oxidizes and returns to its original state, iron oxide. Through an innovative chemical conversion process, Corroseal Rust Converter converts rust (iron oxide) into a stable substance, magnetite. It also primes the surface with a high quality latex metal primer at the same time. Corroseal truly provides one step corrosion control. Corroseal features, water based rust converter with high quality latex metal primer, non-flammable, non-corrosive, easy to apply (brush, roll, or spray), easy to cleanup with soap and water. Eco-friendly alternative to sandblasting Corroseal is the best way to deal with rust because it is less expensive, less time consuming and is much more environmentally friendly than sandblasting. Corroseal eliminates the need to sandblast rust by chemically converting rust from iron oxide to magnetite, a black and inert substance. Don't remove rust, convert rust.

I had read reviews before my purchase. I am glad I did. Using a chip brush to apply the rust converter onto the surfaces was a very good suggestion. I am redoing the interior and trunk on a 1958 Chevy. There were lots of surface rust. I was able to treat the entire floor pan (front/back), four doors, interior roof and trunk with less than 3/4 gallon. Brushing allowed me to make a good even coverage and get the most out of the amount used. This was easy to apply and worked as described. I am attaching photos showing the rust on the floor, Corroseal applied-dried and after spraying primer paint.
Pros: Durable, Easy to Use, High Quality, Looks Great
This product does what it is supposed to do exactly! This saved a roof that would have cost 10's of thousands to replace. I highly recommend this product for rust repair. Love it! We ended up using 15 gallons and covered that with 20 gallons of Diamond Brite Paint. Looks great now!
Pros: Lots of Features

This is the Corroseal over the rusted roof area (in Black) Mid way of the project.
This is after covering with paint. Looks better than new!
Covered the entire frame of my flat bed trailer that is 25 years old. Scraped of flakey rust and brushed of surface rust with wire brush. Applied Corroseal and within minutes the rust started converting to black primed surface. After 24 hours I painted frame with Rustolium oil based black. This stuff is awesome. It does what it claims it can do.
Pros: Durable, Easy to Use, High Quality, Looks Great, hard as nails surface
This rust converter primer works just as described, it went on with a sprayer very well and was easy to see what areas I had covered and what areas I missed as I looked back over the trailer I was painting. I used one gallon to spray the entire 15 ft long x 8 ft wide utility trailer, bottom to top, before applying a top coat. I would definitely use this product again.
It won't work miracles, but Corroseal certainly does an excellent job of combating surface rust by converting it to a protective layer of magnetite. I have used it to restore a wheelbarrow and several hand tools that I thought I would have to throw out because of rust, and am in the process of covering my vehicle's frame as well (the road salt from a dozen winters will do a number on any vehicle). When applied smoothly and consistently, it'll leave a clean-looking surface behind.
Once the metal is rusted through, there's really nothing you can do to bring it back, but if it's not quite at that point yet, Corroseal will convert the rust on contact, thus providing a protective barrier for the metal underneath. Sometimes rust is just plain avoidable, but Corroseal can do quite a bit to slow down and even reverse damage. A gallon is more than enough for most household uses.
All in all, I'm quite glad I discovered this product.
Pros: Easy to Use, Durable, High Quality

Corroseal after application on my vehicle. The body mount, crossmember, and bottom of the frame rail have been treated with Corroseal and appear clean & black; the side of the actual frame rail has not yet been treated and shows surface rust
Just finished painting rails and fenders of my antique car. Scraped loose paint and crud and lightly wire-brushed rust. It produced smooth, hard, black, surface. Next step is to paint with spray can of best black automotive enamel (per directions on Corroseal jug) I don't drive the car in the rain except on rare occasions and I am thinking the corrosealed areas will last way beyond my lifetime. At $50 some dollars a gallon it is only a bit more expensive than good paint and certainly worth the difference when you figure you have to prep down the bare metal when using paint. The time and effort saved by using Corroseal is incredible. Cons: Why doesn't Home Depot sell it in the store?
Pros: Easy to Use, Easy to Install, Looks Great
Cons: only available shipped.should be sold in store too
This is probably an isolated incident but my $60 bottle of rust converter was defective. Instructions on bottle are poorly written and in tiny print. Half of contents was solidified and not mixable. Cut open bottle in an attempt to mix product but impossible to do so. Cant return a cut open bottle. I will not order this type of product online again.
got good results the 1st gal. but the 2nd was full of trash & had to be strained 3 times before it could be used without clogging paint gun!! which caused some waste! recommend straining before use (,something not mentioned on label, in fact both gallons had unreadable labels!!)
I started out applying with a brush then switched to spraying. I should have sprayed it all because I ran out before I was finished. Spraying makes it go much further. I only needed a small amounf additional and didnt want to wait another 10 days so I got Krud Kutter rust converter by the quart. It cost less but I had to prime it afterwards before painting which I didn't have to do with Correseal. I used this on a metal shed and am happy with the results. The only negative is the delivery time.
I used this on a spot of the chassis on my pickup truck as a test before I go putting in all the labor of scaling the rust and applying this product. The spot I tested wasn't even a heavily rusted area. The only direction I didn't follow was to apply a coat of paint after this product dried. My theory is that if this product truely turns rust to a magnite of whatever it is supposed to "convert" this too then it should hold it's own atleast for a little while. This product was on for a month, and new rust is starting to work its way through. Therefore in my opinion it FAILS. It would probably be just as beneficial for me to scale off the rust as much as possible, use a normal paint primer (which is a lot cheaper) and apply a coat of paint, which is required anyway. Other things worth mentioning, this stuff is thick. I wanted to put it in my weed sprayer canister but I don't think it would work out so well. Also this stuff appears to be just a sealant like any type of deck concrete sealer. I say that because you will get the same results covering rust, it will turn black "convert".

Review 11 for 1-gal. Rust Converter Primer
Excellent product! Worked even better than I expected.
I used corroseal to seal my car trailer. The trailer was rusted all over, and under. I didn't want to wire brush or sandblast the entire trailer, so I searched for a rust convertor. The Corroseal worked perfectly. I lightly brushed part of the trailer, but when I was done you couldn't tell any difference between the parts I brushed and the parts I simply covered with the product. I brushed it on and within hours, it was dry, smooth, and black like primer. I have since painted the exposed portions and the trailer looks brand new. I used about 1/2 gallon on a 16 foot flatbed wooden deck car hauler.
This product is very easy to use. Does and excellent job and the fact that it indicates whether you have achieved the best end result or needs additional applications is very helpful. Would purchase this product again. I used it on my 1957 Chevy Pickup.
Pros: Durable, Easy to Clean, Easy to Use, has a professional finish
We used two gallons of this to prime a shed roof (actually, the product comes in bottles that are slightly less than a gallon). It took several hours for some of the rust to turn black but it eventually did. We've put one coat of elastomeric paint over it (another coat to follow if it ever warms up again!) and no rust is bleeding through yet. Of course, time will tell.
Home Depot gladly refunded our money on the unused third gallon ordered. The shed is 20 x 24 and has a fairly steep roof. We thought it would take three gallons. Only took two. We found that a big paintbrush was the best way to apply. The roller didn't get down into the grooves of the metal roof. A paint sprayer would have been the ideal!
It is a bit expensive but it is very easy to use and works quite well. Loose particles have to be removed and then the corroseal is applied. It turns the rust black and neutralizes it. Of course the surface must be painted after the cooroseal.
I used it on the inside of a gas tank that, beside all the rust, you wouldn't believe what was in there. After cleaning out all that gunk, down to the rust, I applied the product by pouring about a pint in the tank than rotated the tank to cover all effected areas. There were some rusted areas outside where I brushed it on. It was much easier to apply with a bursh but, either way, this stuff gets rid of rust better and faster than anything else I've used. You just need to apply it and wait. In thick rusted areas, you will need more than one coat but, the rust will eventually be gone.
Did exactly as described. I am happy with the results. I'd read other reviews prior to purchase. Others recommended brushing it on rather than spraying. I totally agree that brushing it on is the best way. I used cheap chip brushes. They worked good, just pay attention for any bristles that may come off the brush.
Applied this to metal doors after doing some minor rust removal by hand-scraping and then washed off with apple cider vinegar and dried. Product goes on like paint and then turns blue to black when it has changed the rust to magnetite. Used roller and brush for the tighter places. Waiting for 30 days to pass and will apply Rustoleum oil based paint.
Doesn't smell, but will take some effort to wash off hands if allowed to dry. Turns the roller pan, rollers and brush kind of blue/black. It will clean up w/water though.
I would highly recommend at this time for the uses it claims to be good for. I gave a lower rating for value because it is, in my opinion a little expensive.
I used this on a rusty old jeep that sits out in the elements, trying to keep it usable on our lease for a few more years. The product was sprayed on using an electric house paint sprayer and it covered well. The process seemed to work as advertised as it changed colors while drying. 24hrs later I painted over all the treated areas using the same paint sprayer, and the paint went on evenly and bonded very well. It has only been a couple of weeks, but seems to be holding on, so far so good, I would recommend it for similar applications.
