BLACK STAR Liquid Rust Converter - Sealant Primer for Steel Surfaces Turns Rust into Paintable Black Polymer Coating - 5 Gallon Pail

Searched for rust stopper products and found this had great reviews. Bought the quart bottle to see if it was all it says, it is. It brushed on easily. I poured out small quantities into a cup and painted the various rust spots on a deck over trailer I am rebuilding. I painted the major spots at the front of the trailer and the metal plates on the deck over the wheels. I was pleased with how quickly it went after the rust spots, turing black and when dry it seems to be a good sealed surface. I then applied a quick coat of spray paint. I still have to scrape and paint the axles once I get the brakes replaced. I wire brushed the brake drums and repainted them as well. I plan to buy another quart and the spray version to get at some places that a brush can't. This is a great product and I highly recommend it.

This product works very well, I’ve been using it for many years in a body shop and have had excellent results!

Works well converting rust. Easy to apply. Does not come off of surrounding surfaces easily. Stained several areas that weren't rusted but had reacted converter run on to. Have to be careful with it. In areas that are uncluttered and open this works great.

Ok, cleaning up truck from. I used a needle gun, wire wheel and at times a grinder or burr tool. I degreased washed and air dried with compressed air. Trying to avoid flash rust . They stuff worked amazing. I’m not gonna lie. I put 3 coats on. Over a year ago later and it is just as black with blue purple hue. No rust bleeding through. That is where the bed is supposed to be. It is just covered with plastic that blows over and blah blah. So it Det gets wet/soaked whatever you want to call it. UV rays hit it. I’m very satisfied. This summer I’m going to paint it. Def worth the money. I’ve tried some, def not all. I will stick with this over por15 or others. This sticks really good. Just like anything. You have To remove any rust that can pop of later on from driving or whatever, to avoid having to patch up later. It works

I bought this to coat the underside of my Dodge Ram 1500 and my snow blade. I applied it using two methods - brush and airless spray. I am VERY pleased with the results. Before you start your project (while you are waiting for shipping), I recommend watching the YouTube videos from the manufacturer on how to correctly apply it. I personally found them informative.You have to power wash the surface before applying it to get the dirt and flaky rust off the surface, before you start. The nice thing is that you don't need to wait until it dries because it's water-based. You can go in right after washing the surface.For my blade, I was too eager to set up my sprayer (once the rust converter arrived in the mail) and coated the whole thing using a brush. It seemed a lot less efficient and more wasteful because of drips (in hinde sight), but worked great overall. So, if you have a sprayer, I would go that route. The photo here is of my dolly for storing my snow blade. The hard line is the edge of the blade.I also coated the underside of my Dodge Ram, but using an airless sprayer. It took one gallon to do one coat, so if you need to coat the underside of a vehicle, get two gallons.Note: different metals have different porosity and two full coats will likely be needed because the denser metals will require more coats e.g. leaf springs, strut springs, axle, etc. Some of the metals, like the body and fasteners took with only one coat. I would get some chip brushes to help you spread it in the harder to reach areas, as you are spraying.

Used this to touch up the underside of my 54inch mower deck. After power washing it clean, let it dry and applied this and the spray to all the surface rust spots. Turn nice and black when dry, then waited 24hrs before applying the Slip Plate paint on the underside to reduce grass build up!

I got new brakes and rotors and the rotor hub rusted out and it looked hideous ! Cheap china metal ! So I bought this rust converter and it worked absolutely as it said it would.Turned that ugly orange rust black and now I'm super stoked !!!! Great product and only takes a little to get the job done !

This Works no better than the cheap stuff! It absolutely does not harden to a plastic coat seal .it drys to a power with rust turning black. The liquid must simply be a dye because it turns my skin black too. So is it just dying the metal black or actually killing the rust? I could have used the cheap stuff! DONT WASTE YOUR MONEY !
