Description

Don't remove rust, convert rust. Corroseal rust converter is an elite, industrial strength product for all your marine, household, automotive, and industrial rust problems. Extend the life of your metal equipment by protecting it from rust and corrosion. 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 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 is the best way to deal with rust because it is less expensive, less time consuming, and is much more than sandblasting. Corroseal eliminates the need to sandblast rust by chemically converting rust from iron oxide to magnetite, a black and inert substance. Corroseal rust converter is your best rust treatment and corrosion control option because it meets all your metal surface preparation needs by converting the rust and priming the metal surface at the same time.

Works well and provides a nice finish with minimal effort.
Size: 32 Fl Oz (Pack of 1)
I have used another product for a number of years dealing with rust as it occurs on a Freighliner chassis and tow gear and things. I've been surprised at how well it has worked. This product claims to convert rust in the same way but is water based instead of oil based. was a little skeptical about this being a water based product but read some reviews by professional restoration types on other websites that sounded excellent so gave it a try. First, water cleanup is definitely a welcome change. As to the product, the reviews of its long term effectiveness were good. I have no reason to doubt them but haven't used it long enough to confirm them, I have used it in a number of places over the past couple of months and been pleased with the result whether significant preparation was needed on heavy rust or just normal maintenance on light rust as it begins to occur. Follow the directions, including the additional coats indicated by the colors it presents as it dries and I think you will like the results. It will dry to a durable deep black finish somewhere between gloss and semi-gloss. It serves as a primer for paint at that point although the finish looks nice enough, even when applied with a brush ,that the only reason I think I'll paint is to make the adjacent surfaces look as nice as this turns out. I'm even considering just using this although it would make for an expensive paint where rust treatment isn't required. I did some black enameled panels where there was rust I brushed out in a few place and no rust in other places. I coated the whole panel and it looks nice and uniform in the previously rusted areas as well as the rest of the panel. I will definitely be purchasing more of this. ... show more

Best valve with great results
Size: 32 Fl Oz (Pack of 1)
Work amazing, it needs patience (3 hrs or so) AND BEST RESULTS ->surface rust<-. Bare metal results not so good but works more or less. I mix water and solution 50/50 and put in a spray bottle and sprayed on 5X8 tilt utility trailer metal mesh deck, frame, stock rims and all. With some left over in the bottle, Don't get it on your hands 🙌 they will turn them black and then stain them dark blue. Impossible to get off (((WARNING !!! WEAR GLOVES!!!))) ... show more

Size: 32 Fl Oz (Pack of 1)
This is pretty good. I had to put some on a cancerous part of my Jeep where the rear wheel well meets the frame. It is a milky-white color, and is a little more viscous than milk itself - think buttermilk. It goes on easy enough, but it is runny and won't stay put if layered in any sort of thickness. Don't put it in a cheap dollar-store spray bottle unless you want it everywhere, get something better. But understand that you won't be storing it in that spray bottle because this stuff dries up like lacquer and will freeze and clog the sprayer - hence my use of the dollar-store variety. On second thought I should have used a sponge-tip paintbrush applicator, that would work perfect for this. It works great once on the part, I first took a hammer to knock off the gobs of rust flaking off to get to a solid surface. It started to turn black after 5 minutes, and only got darker. 15 mins in it was pretty much done, and starting to dry. I let it dry overnight and it formed a good coating that should survive this winter, until I can get under there to repair it properly. ... show more

Wow...amazing stuff! Easy to apply, takes any kind of paint for top-coat (or none at all).
Size: 32 Fl Oz (Pack of 1)
It's just TOO EASY! Paints on like buttermilk, turns to black (magnetite) on rusty areas, dries almost clear elsewhere. No fumes, no complicated process, just remove loose rust, paint on with a foam or bristle chip brush (I've even used a pump sprayer) let it dry for an hour (max) and then paint -- or NOT. The black magnetite coating is quite rugged all by itself. ... show more

Fantastic
Size: 32 Fl Oz (Pack of 1)
Bought multiple times. Once metal is prepped, this product changes remaining rust’s molecular structure into a solid satin black surface, perfect for receiving paint. Used it as primer on wrought iron and it looks like the finished satin black coat, which is wonderful when you can’t get to paint right away. ... show more
