Corroseal-82320 Water-Based Rust Converter Metal Primer, Rust Converter - 1 Qt

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.

Worked great to seal in some rust on an antique candle holder. I added two layers of primer and two of paint. Good as new…

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!!!)))

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.

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.

This product is awesome Out of all of the rust converters I have used over the years this has worked best for me. The only problem which is likely user error from leaving gallon jug in garage that is not climate controlled over time it settles and gets hard. Instead of purchasing the gallon and chancing it settling out and going bad over time, I decided to purchase the 32oz bottle which seems to be a great size and I will typically use the entire bottle fairly quick so no chance of going bad. If I need more I’ll just order another 32oz bottle. Researching this type of product it is best to store in climate controlled area if storing for long periods and is a good idea to flip jug end for end every now and then when you walk past it to prevent it from settling out.

I've used this a few times it works great and is a pretty good value!

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.

Increible producto, sencillo de usar y seguro. muy efectivo siguiendo el proceso el cual no es nada complicado. lo seguire comprando cada vez que tenga un problema de oxido

Muy caro pero muy bien y facil.

MUY BUENA CALIDAD

Fácil aplicación

Esperaba una jalea naval, pero es un inhibidor de óxido de pintura imprimación. Funciona muy bien y se vuelve negro cuando está seco. Estoy muy contento con él y sólo usamos media taza para tratar una gran mesa de patio al aire libre.
