Corroseal Water-Based Rust Converter Metal Primer, Gallon, 82331

I first ran across Corroseal about 10 years ago when i got a small sample bottle at a work boat showI used this sample around my house for small rusted objectsI must say i learned that this product does wonders when it come to converting rust.No doubt the best product i have ever usedI purchased a fixer uper Bush Hog for my tractor which had some pretty heavy to light rust recently.I knew right what to do, i purchased a gallon of Corroseal to tackle this project!Awesome stuff!

I have a 15 year old utility trailer which sits outside in the elements in south central Florida. Needless to say it is pretty rusty. In fact I was going to give it away and buy a new one. Then I ran across this product and decided to give it a try. Also I decided to do this in July and August which is our rainy season and very hot and humid conditions. So I put the trailer on blocks so I could get under it. Then I pressure cleaned it. Also I did some grinding with a wire brush attachment on my cordless drill. And sanding mostly on the fenders which were the worst. Then I began applying the Corroseal. Mostly I applied it with foam brushes. When it interacts with the rust it turns purplish black, otherwise just black. If it rains that which has been applied that day will tend to turn milky white but then as the moisture dries out of it - it turns purplish black again. It never rained until the Corroseal I applied had been set up for at least a couple of hours. Actually it only rained on my party a couple of times - probably three. Then when I applied DoItBest's version of Rustoleum over the Corroseal. I used flat black which actually came out very nice. There was a small hole in one fender and I cut out a piece of galvanized sheet metal I had laying aroung and epoxied it over the hole. Worked pretty good.I am writing this review 5 months later and have to say I am very happy with the project and now my trailer will take the elements much better.

I was concerned with some of the negative reviews here, BUT... I got this anyway, AND... This stuff seems GREAT. So here is the method to the madness: I was using it on an old farm running gear that had been in the ding weeds for eons. Get the barnacle rust off. Do not grind down to bare metal. Just steel brush it to get scale off. This product converted all solid surface rust to a hard black enamel within minutes to hours. It goes on easy like milk. Put it on with a brush. Coat evenly. DO NOT put left over product back into bottle as it will compromise the remainder. Use whatever you pour out. I painted over it a few days later with industrial oil enamel by brush. Looks brand new. ALSO, do not leave whatever you are working on out in the rain. It will turn back to white until it cures again. But that's a NO brainer to most of us. Not sure how long it lasts...? But I'm guessing I won't have to do this again for many years from the looks of how well it worked and how hard it made the surface rust. I used it on the rims too. Perfect outcome so far. Let me know if this was helpful to you :-) Simply put, IT WORKS!

I bought it to fix up a used trailer. It works great and provides a very protective coating ready for painting. Note - I bought a gallon because I was unsure how much I would have needed. The smaller size would have been fine for the trailer - First pic is the rust sanded, Second picture is with Carrousel applied and third picture painted with Rustoleum

This is a great product, as others have said. I'm writing this review to provide some extra information for those who are applying Corroseal:I am in the process of applying the product to wrought-iron patio furniture. The consistency of the product is quite thin, but it must be applied in a heavy layer to areas of rust. This means you cannot apply it to vertical surfaces as you would paint (it will drip off and not seal) - instead, you need to apply it to flat surfaces only, and therefore will need to reposition an object after the initial coat sets so that you can coat other surfaces. In my case, this means coating the seat of the chair, waiting for it to dry, laying the chair flat to coat its back, and so forth. I've been using a small sponge brush which is doing a very good job. The product dries fairly quickly and, as others have said, performs alchemy. Usual precautions, clean up with soap and water.

Worked OK, but pay special heed to the comment that the surface must be 100% rinsed clean. I descaled my 5x8 trailer, then scrubbed it with a degreaser-soap mix and rinsed it. Several areas did not turn black, which I can only attribute to less than 100% rinse.Otherwise, great rust sealer and primer. Trailer turned out great.

Just used this on my 1994 Jeep floorboards. My Jeep spent most of its life salt-free in Wyoming, so its a rare Wrangler with no structural rust.However, it had some rust on the drivers side floorboard from water getting in and pooling there under the carpet.Two applications of Corroseal turned all the rust black and made a primer-like surface. I spray painted Rustoleum bedliner overtop of it and did the underside just for a little added protection.The results look great (in rough and ready Jeep with patina terms :). ). I’ll be surprised if it doesn’t stand the test of time. It is hard to imagine any rust getting going again. Rather expect the water to just puddle on the surface and be easily drained or wiped up.

Really Like This Product. Used it for front step Iron Railings. The railings look the best they ever have. Sanded them first with a brush-screwgun type sander then power washed them and let dry. Then Corrosealed. They came out great - I almost did not need to paint the black with rustoleum paint but painted them later anyway. I Hope this lasts for a good number of years.Also, this product was great for garden statues made of metal. I've posted two squirrels statues I had. One coated with Corroseal, the other without. What a difference. The Corroseal coated statue came out jet black and looks nice. The photo shows one with and the other without corroseal. No paint.

I found out about this product on You Tube where someone did a follow up one year later and the bottom of his car still looked good and he lived near the beach!

Worked great on a rusted chest freezer. Easy to apply and dried fast.

Am using this on some rusty green house pipes we were given. Works great. Some spots I had to apply two coats on but as rusty as these pipes were that did not surprise me.

1st time user so didn't know what to expect. This stuff is miraculous. I used it on my neglected and rusty smoker after a light sanding (EXTERIOR ONLY).

Restoring an old IH scout, and treated all the rust before painting with tractor enamel. Product sprayed nice with a HVLP gun, and 1 gallon was more than enough to do the whole...

Bought this as it was the most recommend despite the price. Followed the manufacturers instructions as seen on YouTube to the letter even buying and using a descaling tool.

I bought this to clean up the rusty wheels on my car. I watched the YT video pf Gempler's reps restoring a rusty wheel with this same rust converter.

Works great! Hope does well in a long term!Prepare the area before applying this product for better results

This stuff is awesome!! Puts a very nice patena on rusty metal. Have also used on pottery.

It work perfect cleaning the motor of my car,
