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

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.

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.

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.

creates rustproof surface enabling painting without wire brushing (except for thick, flaky rust).

works exactly as described

It works well on rust.

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,

Love this stuff, I apply it to the bottom of my car doors and tailgate. Anywhere that are common problem rust spots up here in the Northeast. It slows that nasty rust down.

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.
