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 4 reviewers.
Rated 5.0 out of 5.0 by This product is fantastic for rust conversion. We are renovating a heavyweight, all-steel 1928 Pullman Sleeper railcar for handicap accessibility. Needless to say, we've run into a LOT of rusted steel. We used this product to seal all our interior walls, metal studs and floor surfaces. It dries completely sealing the surfaces turning rust jet black. We even test-sprayed the surface with water with no re-rusting. Old galvanizing or contaminated surfaces cause funny colors but the surface is still dry to the touch with no tackiness and completely sealed. This is GREAT STUFF! May 18, 2012
Rated 4.0 out of 5.0 by I have used other brands and this is as good if not better than another brand Good to great product. Will buy it again for another project December 10, 2013
Rated 5.0 out of 5.0 by Worthwhile I have an old steel garage that was in rough shape. I sanded it lightly down and used this product. Indeed it converted the rust into some other black metal. It also primes well, creating a thick, almost plastic/rubber like coating, sealing some gaps in the metal. I used sherwin willians DTM latex paint over it and it turned out nice with a single coat. It's expensive, but sure beats sanding to the bare metal. April 23, 2013
Rated 5.0 out of 5.0 Best product ever, In refinishing my houseboat I used Corroseal to cover the rusty areas around my pontoons prior to the final painting. This product was very easy to use and within minutes the rust was converted. I purchased a gallon and have plenty left for projects around the house. October 12, 2012
