Opsho, Prep & Etch, Corroseal, ect?

[WanderlustExistence]

Which is best and why?

Obviously there is a huge price difference. Is one safer than the other? Does one work better?

They are basically the exact same product, Ospho is just 3x's more proud of theirs.

😂🤣 Ah, okay. I gotcha. Thank you.

So if I use etch one, can I paint over after or do I need a primer too? To my understanding it was a primer too.

What kind of mask do ya reccomend? I've just been getting the 3M disposable ones from Lowe's for different things.

[o1marc]

Read the directions, some want you to wash it off before paint

[WanderlustExistence]

Yeah, I figured. Just wanted to make sure there wasn't a need for a primer in addition to the paint. The floors have been a pain in the ass. Trying to remove the paint that was there before us is no fun and taking much longer than we hoped.

Out west at least, Rust Mort seems to be the best product. It is a bit pricey at $19 a quart and it does need to be rinsed before painting--but then all the rest should be too. Lately and for small quicky jobs I have been using up a gallon jug of Krud Kutter I picked up for 4 bucks at the habitat for humanity re-store. The latter works fine for converting surface rust on otherwise clean steel but for more crusty stuff I'll continue to use the high price spread. Jack

Corroseal is totally different than ospho. Have you used these products?
Ospho is only $25 a gallon here, man.
It goes a long way.

Rustoleum Rust Reformer is the absolute best rust converter I've ever tried.
NOT the spray cans, the gallon stuff.

Thanks so much for the info. I saw that one too. What's the difference? I am on a budget but if I don't have to prime before painting then I'm saving money there. I've seen people use all of these but just not sure which way to go. Ospho here is 50 a gallon.

I'll check that out. I've been using Krud Kutter which has helped a bit but we've got a lot of paint/glue that is literally needing to be scraped up. It a been a lot more work than we thought it would be. I'm hoping to get a pressure washer to see if that helps make things faster.

Have you got an ACE Hardware near you? Here in NC Ospho is only $26 a gallon.

And when doing your research, it's just as important to research whom you're taking advice from. Much better to garner information from people who've actually done the work vs. someone whose only proficiency is clicking on the "Submit Reply" button.

In FLorida??
All our local Ace Hardware stores have it for $25 around my area of central FL.
For $75 a gallon the Rust Reformer is AWESOME stuff.
I've used Ospho since my days in auto shop class after high school. I put it on any bare metal I come across before painting.
But for serious rust like on a frame, the rust reformer can't be beat.

This is the stuff-


I got mine from Walmart.com.

A little goes a long way!

[WanderlustExistence]

Thanks so much everyone. I will check Ace, I think there's one about an hour away. I thought I saw it online for 50 there, but I'll double check for sure!

That is if you actually know how to do research other looking at the bottle on a shelf and offering a price only for something different (yet the same).
1st off, I have been using rust converters in my business every week for the last 10 years, so I know through experience what I speak. No one here has seemed to express just what Ospho is and how it compares to other like products. The name Ospho is a brand of rust converter that's main active ingredient is Orthophosphoric acid, the same active ingredient in Prep & Etch , Skyco, etc. in the same percentages, making them all the same basic product depending on the different inactive chemicals added.
Ospho brand seems to be mush more expensive no matter where you get it. Ace Hardware is notoriously known for being high priced, but convenient. The carry the midpriced Skyco product. If you're building a skoolie, chances are you'll be going to Home Depot quite a bit. They carry Prep & Etch for less than $16.

Next time you hit that "submit reply" you might actually try some useful positive input.
