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.

Rated 4.8 out of 5 by 64 reviewers.
Rated 5 out of 5 by Great product 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! July 9, 2014
Rated 5 out of 5 by Handled the job very well! 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. August 27, 2014
Rated 5 out of 5 by Converts to hard-as-nail surface. 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. September 19, 2013
Rated 5 out of 5 by Excellent rust fighter 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. April 30, 2013
Rated 5 out of 5 by Seems to work! 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! November 19, 2014
