Black, Rust-Oleum Automotive Rust Reformer-248659, 8 oz

Followed the directions, wire brushed a spot, washed, dried, applied and it was maybe a little longer than 15 minutes but not more than 30 and the rust was black. It appears to leave a gloss clear coat. I'll prime and paint after three days as instructed.

This is an excellent product; I have used it for years. Quick dry and water clean-up. I have used the aerosol and the this brush on, but I find the brush on is the best. Follow the directions on the container---its put on there for a reason. Top coat as directed thereon and you'll get good results.

Used this on corroded fuel tank straps after removing the loose rust and wire brushing. The straps came out looking like new. The Rust Reformer turned the rusty straps black and they look great even without painting. When the weather warms up in the spring I'll be using this on my brake drums.

I purchased this product to stop the rusting of the wheels on my car where they are exposed through gaps in the wheel covers. The wheels were originally black, and had become rust-colored, but the rust had not progressed to the point where the metal was pitted. I had hoped that the Rust Reformer would turn the rust black, both stopping more rust from forming, and eliminating the need for painting. It did react with the rust and turn it mostly black, but there was still a hint of rust color in spots, so I followed the directions and topped it with a light coat of paint after waiting 24 hours. The wheels look great now, and I don't expect them to rust again. I used a similar product on the rusted cast-iron hardware on my 1930's garage door some 20 years ago, and it has only now started to rust again. I plan to use the Rust Reformer left over from this project to touch it up so I can go another 20 years.

I have been using Rust Reformer for years on our wrought iron patio furniture, Apply with foam brush, it goes on milky white, and after few minutes, turns satin black. Fantastic product

I have a lot of problems with the rest of my RV trailer frame. I tried rust remover's and they didn't work very well, I tried this stuff and it works great! Because I had to brush it on however I would not use it where it's real visible. It's not even enough. I was able to paint right over it with paint after it dried,

This stuff is fantastic. Had an older utility trailer I was replacing the boards, the metal under the old boards had really rusted badly .Gave it one coat of rust, reformer let it dry then put rustoleum paint on top of that before adding the new boards. Turned out fantastic and I'm sure it's going to last a lot longer.

Really good stuff, but if you read the instructions, you're actually supposed to wait 3 days before priming and painting. If you brush it on, expect well-defined brushmarks as part of the finish.

I prepped the rusted steel areas to be treated with the Rust-Reformer product by first scrubbing it with SOS pads, then rinsing, then scraping more heavily rusted areas to remove "rust bumps and flakes" then wire brushing all rusted areas. The product is easy to apply and clean-up is a breeze since it is water-based. It goes on white and gradually changes over to black as it dries. After one coat, I was surprised and disappointed to see that under direct sunlight areas of rust colored metal were visible under the first coat of the product in the same areas where scrapping removed the "rust bump and flakes." Apparently scrapping and wire brushing are not sufficient to properly prep the deeply rusted areas. Had I known, I would have fired up my palm sander to take the heavily rusted areas down to almost bare metal. Where the rust was slight/superficial. the product did indeed convert the rust to a black inert surface. Too bad its penetrating power isn't up to snuff for more heavily rusted areas. Additional coats of the product over the the areas that had deeper rust did not penetrate the first coat and left the rusted areas visible under two coats when viewing under direct, full sun. So be prepared to really prep the surfaces if you have anything BUT shallow, surface rust only.

I was disappointed but i have nobody but myself to blame. They discribed the probuct. I didn't realize it was a paint on product until it wàs in my hands. I tried it and really didn't like how I couldnt sand out the runs. Thank Goodness i experimented on a lamp base before i used it on my antique rot iron bed frame. Like i said it was my falt, what i needed was the brush on or spray on rust remover by Jelly Belly i believe.
