Anybody Use Ospho For Rust Removal

[Sawdust]

I’ve only used two types of rust treatments when rebuilding a few GT’s. The self etching primer that looks green was the best. I have an MF12H that’s been primed and boxed up for around 22 years with no rust popping up anywhere. The other was Rustoleums rust reformer. I’m not happy with that. I noticed it dried very fast indicating not much time activating against rust. A few months later I noticed rust coming back. It basically just encapsulates the rust.

I watched a YouTube video a few days ago where a guy used this Ospho with very good results. I ordered a quart bottle from Amazon at $21. where Ace Hardware listed it for $17. but not in stock. I’ll do a follow up on it once I use it.


Here is the video it’s worth watching how he compares several different products.

Heard good things about Ospho. I've used corroseal in the past, it's done pretty we'll.
I also have used concrete and metal prep/etch that I got at either Menards or Home Dropout. It works like corroseal, spray on let dry them paint over. I do wipe off the white reisdue though.

One of the best things I've ever used has been Rustoleum heavy rusted metal primer. I painted a small trailer back in 1994 with the primer and a brush. It lasted 20 plus years with no top coat before any rust showed through. Getting pretty rusty now but I just use it as a water tank trailer for the animals.

I use Ospho on all of my tractor and metal projects. Been using it for about 30 yrs. Lots of the local fishing fleet used it on their boats. Figured if it work on boats in the salt water it would be plenty good for my projects.
